That a great question. That might be a royal PIA to do. But I was thinking more about the whole Licensing and Copyright questions. I was wondering how businesses that sell replacement train parts deal with this. Or maybe they don't?
Anyway....if I hear from @Buco or anyone else that's in need of replacement Trainmaster truck sides (again, the mold is made from a Williams engine, not a WBB engine, the part configuration c/be different) to try a cast again with a different resin, I will. Otherwise I'll just chalk it up to a learning experience and having fun.
