Can anyone help me with identifying this pullman car and the approx, date they were made. My neighbor has two of these, this is the combine, both NYC. They were made in Detroit, MI but they have no markings whatsoever on the car. There are no lights, no operating couplers and no windows. The car weighs 4 lb. 9 ozs. and is about 22" long. They will run on O scale track. The floor is like a shiny fiberboard. Also what sort of value would you place on this? Thanks.
By the way there is a nifty 50's video on You tube of Congress Tool and Die and how they make the dies and do the die casting. Mostly they made auto parts and pulleys.
