I just noticed that some of my Gondolas have a Bettendorf short-shank coupler/truck on one end and a medium (or long?)-shank coupler on the other end.
I first noticed this on one of Gondolas (CB&Q 82044). I buy a lot of rolling stock used so I figured the previous owner might have swapped the truck on one end to facilitate small-radius curves. But after looking at several other gondolas, I noticed the same thing, including on gondolas I believe I purchased new.
Does anyone know if this is some kind of weird fluke or if it is standard issue for Micro-Trains?
