The last item I still had to install on the deck or bulwark: the navigation lights. That immediately proved to be a major challenge.

There is also a drawing of:

They are mounted on the bulwark on two separate irons, each with two 90-degree angles. On the back of the wooden boxes are two brackets in which the irons can rotate.
While sailing, the boxes can be moved outboard, and when mooring alongside another ship or the quay wall, they can be rotated inward.
The irons are inserted through the handrail and each rest on two angle brackets, allowing them to rotate at a controlled angle.
The original construction already looks fragile ... and then there's the 1:50 scale ...

The result, after many hours of work with various versions that didn't work:

The irons are made of 0.8 mm wire. The boxes are made of thin plywood.
This is how they are turned inward:

"Of course" they can also be turned outward:

This is a very fragile structure, and after taking the photos, I removed them from the bulwark and put them aside. The risk of them getting caught on me later when I continue working on the rigging is far too great.
Just a few more small cleats on the handrail, and then I can start on the masts and rigging. I need to do some preliminary work on that first. An old specification describes each line's length and diameter. As do all the blocks' length, width, number of sheaves, and whether or not they have a hook or an eye.
