I am hoping someone can help me with a project I am working on. The car is a 1945 DD boxcar, 10'6" height cars with 14' door opening (two 7' doors) that were of the interim improved youngstown design with the 5-6-5 corrugations and the wide seams. Can any of you point me to a source for suitable doors in HO scale (even if they might have been in a resin kit at some point)? Any and all assistance is greatly appreciated.
