You are on a good way with you Harvey.
I have a small hint and comment if it is allowed.....
Due to the fact, that you installed the guns already completely, I interpret this, that you do not want to blacken the muzzles and will keep them in the brass color.
What I would is maybe to color the trunnion cap / cap square in black
I marked this part with the red arrows - on original carriages it was much shorter and bended, in order to take over the round trunnions of the muzzle. Here the detail of the kit is (let us say in this way) incorrect
with some paintwork the wrong form of the caps will be not so prominent
Good, that you try to improve them - you will realize the difference afterwards.Thanks Uwek! That's really helpful actually. I can easily sort that out and remove the trunnion caps. I wasn't aware that they looked like that so really good to see the images. I will sort it out and let you have a pic once it's done. My OCD will never let that go once I know it's wrong
I must admit I just assumed that Harvey's guns were small enough to have been cast in bronze as opposed to iron. I guess not so painting would be sense. All these things to think about before putting them all together. Anyway given I'll be taking the caps off anyway, it will be simple to paint the guns. I'm assuming I paint them? As opposed to some other method of blackening?
