As I said in my earlier post, contact Macs Mouldings and he may produce it for you. Tell him the size, he does 1/24th and 1/48th already.
I wanted a radar for a 1/12th lifeboat, if you look at the one on his web site I gave him the drawings and he prduced it for me and now stocks them for others. They come at a good price to.
