Hi, Great model!! Just looking at it makes my day!! Good work!! I 've been thinking of building me a roundhouse for my layout since the commercially available ones just don't quite suit my taste. I'm looking to match the style of the Muir Models single stall engine house which I built a while ago. Where can I find the materials for this project?? I would be needing clapboard siding, beams of different sizes, cast metal (or plastic??) windows, doors, etc. I also need suitable hinges for that engine house, since the ones that came with the kit are really too far off-scale--they scale up to about 4" thick!! Thanks for any input you may have. Gus.
