Bernie,
Believe it or not, I am still committed to modeling the C&O in some manner. That said, I am presently dealing with space constrictions for my door layout, let alone a module for this project. So, while the A&R door layout still resides at my other house twenty-five miles from my residence and I'm, unfortunately, non-productive on it, I may be able to talk the wife into allowing me to build a 2' x 4' module. No promises, though, but is there something that I might be able to build in those parameters that could be productive for this project?
