Hi, I'm building the D & NY traction engine in 2 in Scale, and i'm fabricating the cylinder etc at the moment. The main body is cast iron and the valve chest and top cover are gun metal, but the valve chest cover is made of cast iron. I want to make this in gun metal as well so that it can be polished when finished. Does anybody know where I can get a piece of cast flat gun metal 2 in x 2 1/2 in and about 1/4 in thick.
Thanks
Garry
