I need a reminder please regarding the Branchline Blueprint 50-foot boxcars in terms of the variations. I know they produced an 8-foot door car and an insulated car w/a sliding flush door. Note, I am not interested in the more modern cars they did, only the ones that would have the Improved Dreadnaught end variations.
Did they do a 9-foot door or any double door examples? Did the do any with a lower straight side sill?
