In Februari 2021, Lemke-LeGrand came up with this photo of the development of a 1:8 scale model of the Mercedes-Benz 300 SLR Uhlenhaut Coupé:
001 LeGrand Proto.jpg
It's a still from their Video: --> LeGrand 300 SLR Uhlenhaut Coupé <--
There expected delivery: December 2021.

The model is based on this historic Mercedes: --> MB 300 SLR Uhlenhaut Coupé <--
006 300 SLR.jpg
Only two were built: 'der Blaue' (the Blue) and 'der Rote' (the Red)
For those interested, the link to the --> MB Archief <--

Lemke-LeGrand didn't make the expected delivery in December 2021.
From that point on, I continued to monitor the development.

Deliveries didn't begin until the spring of 2024, with the first "der Blaue" with a blue interior.

The expectation was that the "der Rote" would be delivered in the fall of 2024, but this was repeatedly postponed because they wanted to fix some shortcomings and update the manual.
But now, deliveries of the second version, the "der Rote" with the red interior, have begun.

There are some minor detail differences between the two.
On the "der Blaue" (Blauer Blue), the fuel filler opening is through the rear window, while on the "der Rote" it's located under the tailgate.
The "der Blauwe" has a rectangular mirror, while the "der Rote" has a round one.

LEGRAND Mercedes-Benz 300 SLR “Uhlenhaut Coupé” 1/8 kit – “The Red One”

The original: Daimler-Benz developed this coupé version of the 300 SLR racing sports car for the 1956 season. It was designed under the supervision of Rudolf Uhlenhaut, then head of the MB racing car department. The nickname “Uhlenhaut Coupé” is a reminder of this today. However, it was never used in racing because Mercedes Benz withdrew from motorsport after the end of the 1955 season. The MB 300 SLR is one of the most spectacular and expensive super sports cars ever built and was already way ahead of its time.

Mercedes-Benz auctioned the original vehicle with the red interior (No.008/55) at the Mercedes-Benz Museum / Stuttgart in May 2022 in a spectacular auction for the record price of 135 million euros to establish the “Mercedes-Benz Fund”.

– Cylinder 8
– Displacement 2982 cm³
– Power 302 hp (222 kW) at 7500 rpm
– Top speed 290 km/h
– Production period 1955
– Number of units produced 2

The kit: LEGRAND 1/8 kits are made from high-quality materials. The body of the model, which weighs around 7 kg, is made of die-cast metal and is already painted. The kit of more than 900 parts is easy to assemble and contains parts made of various materials such as metal, rubber, textiles and high-quality plastic. Most components are screwed and plugged in. If there are only a few parts, we recommend gluing with a model making adhesive. The steering and suspension are functional and the doors and flaps can also be opened prototypically. The model pictures show hand samples. Series production may differ in details.
– Kit contains more than 900 parts
– Dimensions LxWxH mm: 550 x 210 x 160
– Weight: approx. 7 kg
– Easy to assemble, many screwed components
– Incl. Screw box
– Metal body, ready-painted
– With Eberspächer silencer (optional)
– License note: Mercedes-Benz and the design of the enclosed product are subject to intellectual property owned by Daimler AG. They are used by LEMKE Collection GmbH under license.
=================================================

And why an Eberspächer silencer was made for the car?

--> This Sound <--wasn't allowed for a while now either. It's a clip from a longer video.

The kit is priced "seriously." But thanks to my pre-order, I'm considerably lower than that.
In terms of quality, this kit is supposedly even better than Pocher's. I'll see if this intermediate stage can be realized:

Yesterday I received the message that the parcel service would deliver the package this afternoon.
Hopefully, I can give a first impression of the kit soon.

The package driver carried a large box on his shoulder:
007 Package.jpg
Weighing quite a bit:

Stripped of its sturdy packaging, this box emerged:
009 Box.jpg
The building instructions: 117 pages, divided into 6 groups with 106 clearly illustrated building steps.
010 Groups.jpg
Neatly packaged parts in the group boxes:
011 Bags.jpg
With 36 different types of bolts:
012 Bolts.jpg
With very securely packaged metal parts:
013 Metal Parts.jpg
Besides building the Balder, I'll be busy with this one for a while. From what I've seen, it's already very detailed. Let's see what other details I can add.

Wow! Looks like you’re stocked up for a whole year of fun — maybe several! Now I’m wondering… are there functional motors for this model at that scale? I mean, if everything else is working already, why not the engines too? Might as well go full Frankenstein on the model!

For sure I will have fun for ‘some time’ with this build, Jim. I am a builder of static model and have nothing with RC.
For sure @François can design and print a ‘working’ engine for this model. But as well as the Ducati's a look at the detailed outside of the engine is enough for me.

Agreed, a working static model seems like a waste of effort in my opinion. It’s meant to be displayed, not played with. That would only encourage people to touch it…no thanks! I always tell people to look with their eyes, not their hands! ROTF

…though having a working engine doesn’t automatically make it an RC model. The engine could be turned ON while the car was displayed in the cover. This model is designed with working doors, a boot, and a bonnet. ;)

Yes…my Porsche 917 has working doors and a rear hatch that lifts up, and a front hood for access to brake reservoirs, etc. that is removable. However, I do not ever touch these or let anyone else because it’s in a case. So functionality that is mostly useless unless you want to display it with the doors open and the hatch up, in which case I need a larger display! ;)
 
When I start building a special model, I always want to know more about the background.
W196S:
The "Uhlenhout Coupé" is based on the W196S, the open racing car that Mercedes-Benz entered in the Formula One Championship in 1954 and 1955:
014 W196S.jpg
A nice YouTube video about the W196S and some famous people:
The Uhlenhout Coupé is based on this W196S. Rudolf Uhlenhout wanted to offer drivers an alternative for endurance races with a closed coupé.
The first build was "der Blauwe" (the Blue), chassis number 196.110-00007/55.
The second was "der Rote" (the Red), chassis number 196.110-00008/55.

However, neither Coupé ever competed in a race. In 1955, a test car crashed. There's a whole Wikipedia page about it:
The driver and 82 spectators were killed.
The special Elektron body material posed additional problems. They tried to extinguish it with water, but that only worsened the fire. It has a high magnesium content.

Both Coupés were converted for legal road use, specifically for long-distance testing and to allow the press to drive them and gain an impression of the Mercedes-Benz technology. This led to the development of the Ebenspacher muffler.

I started working on getting a first impression of the manual and parts, so I could also write a short review for this kit.
The first two pages provide an overview of all the parts and bolts required for building Group 1:
015 Group 1-1.jpg
Source: the link on the Lemke-LeGrand website, but also via the QR code shown later in the manual.
016 Group 1-2.jpg

Group 1, step 1:
017 Group 1 Step 1.jpg
Also collected the parts for this review:
018 Group 1 Step 1.jpg

Group 1, step 2:
019 Group 1 Step 2.jpg
Assembled step 1 with the parts from step 2:
020 Group 1 Step 2.jpg
P.S.: Here, the parts are upside down, the parts marked 'R' and 'L' can be confusing.

You can then compare the result with a photo in the manual:
021 Group 1 Step 1+2.jpg
There you'll also find the QR code that leads directly to the Lemke-LeGrand iCloud website, where you'll find all the photos of all the steps and the digital manual.

Some parts are mirror-image identical. You could interchange them. However, the parts have small 'L' and 'R' markings:
022 Marks.jpg

All in all, it's a bit clearer than the Pocher kits. The bolt fit is also better. You need less force with sufficient friction. You don't have to worry about the bolt breaking, and you don't need to pre-tap the holes.
So far, all metal parts, except for the silver-colored rectangular block. It's no longer in a cast frame but has already been removed, and I can't find where it was attached.

Hello,
I built the « der Blaue », and good luck with the shelving!

I found the model to be of good quality.
Thanks for your visit, Joone. They took about almost 1,5 year to correct some not nice fitting parts at the LE102 'der Blaue' and to rewrite some parts of the manual. Hopefully less problems with my build ....... ;)
(Found already a fault in there 'new' manual. Send a e-mail to Lemke-LeGrand. Let's see how the react ......)
Regards, Peter
 
Group 1, step 3-1:
023 Group 1 Step 3-1.jpg
Two interesting parts right away: the drum brakes.
Here's a look at the previous photo, with the front brakes circled:
024 Drum Brakes.jpg
Rodolf Uhlenhout opted for large drum brakes because he wasn't entirely confident yet with the recently invented disc brakes.
Specs: inboard duplex drum drakes with power assist, Front: 350mm (13.8 in), Rear: 275mm (10.8 in).
Because he wanted to keep the unsprung weight as low as possible, he placed the drums on the inner fixed parts of the axles. This allowed him to install larger brakes that otherwise wouldn't fit within the wheels.

Group 1, step 3-2:
025 Group 1 Step 3-2.jpg
026 Group 1 Step 3.jpg
The rear suspension and drivetrain are starting to become visible. It started with some small color accents using graphite. In the photo with the circled drum brakes, you can see that the brake segments are interconnected on the inner side. They are just visible on the insert at the top left. This will no longer be visible on the model at this rear axle. Maybe on the front axle. Anyway, it's just fun to add something yourself. Of course, you can also just bolt everything together ....;)

I find all the silver parts together unattractive.
027 Group 1 Step 3.jpg
That's why I gave the stabilizer bars and the brake drums a light wash to add some subtle accents.

Because brake fade sometimes occurred in long-distance races, he designed an innovative air brake for the 300 SLRs that could be activated by the driver:
028 AirBrake.jpg

Enough building work on the Uhlenhout Coupé for now. It's the Balder's turn again.
Regards, Peter

Peter, mon ami! This is a fantastic build, and not just because of the quality of the work (as expected). Your build log is incredibly informative and genuinely enjoyable to follow, something that’s not easy to find. The way you explain everything makes this a great learning resource as well as a pleasure to read. Many thanks for taking the time to share both the build process and the knowledge behind it.

Thanks for your very nice words, Jim. That's almost become my standard when I start working on an interesting kit or scratch build. I want to know the history and background. In the past, like when I started with my Robert E. Lee, I visited various libraries at maritime museums. Now it's much easier with the information on Internet. And once I've found it, it's just easy to share it with others. That makes it much more interesting than just a report on assembling the parts.
