I assume Jeff English will answer this, but I've sent it to everyone since I'm probably not the only party interested in the response.
Rutland Car Works is selling a resin kit (HO scale) for an MDT reefer series built between 1911 and 1917 for the NYC (series 155000-155999 and 156000-156999), LS&MS (series 145000-145999) and Michigan Cental (series 16000-16249). These were truss rod cars with 5-foot door openings and four hinges on either side of the door. My question is whether anyone knows if these were still running in 1947 and if so, in what quantities? The number series for the cars changed when they became MDT cars. Thanks. Ted
