Just so we're all on the same page, the car pictured (the one I am asking about) is a poultry car - used to haul chickens, turkeys, etc. It's not a stock car that's used to haul pigs, sheep, cattle or horses. While I imagine poultry can smell, I somehow feel we've lost sight of the topic.
Eric, the pic was for a N scale REA boxcar on eBay. I'm a little confused.
Richie's reference to the Lionel cars made me look harder at the photo and I think I can make out the word "Palace" above the interior wheel of the left-hand truck and "Poultry" just below the door, toward its left. Palace Poultry? Again, I appease the group for some facts. It seems rather Monty Pythonish to base knowledge of the proto on Lionel models.
