(My reluctance is on account of the fact that these are very complicated carriages to build)
I'm able to re-use most of the moulds I made for 150 so while I had the resin out for making the lamp holders for 19 I decided to cast a set.
The only major alteration on this carriage is that the front needs to have a very subtle curve on it.
So what I've done for that is very gently reshape the master I used for 150 - which was a composite piece with a brass backing and styrene moulding detail on the front - and I'm going to make a fresh mould from that.
It's not in the shot above because it's currently sitting in a bath of gooey RTV silicone rubber - I'll post a before and after pic once I've taken a casting from it.
