Mike asked, "Were you able to put a manu date on the #3011 Vinegar car?"
I don't think we can do better than a range on the manufacture of any of the A1G line.? We can usually get close on when a specific body style was introduced, based on the first time it was advertised and/or mentioned in a model railroad magazine or other source.? I don't know this for the vinegar/water tank car though.? As I get to the Model Railroaders of the late 1960s there will be Atlas N Gauge advertising and likely product reviews as well.?? I'm now up to September 1956 so only about ten years to go!
If only I weren't distracted by (a) the day job and (b) the unearthing of my hard copy stash of Railroad Modeler magazine, which started in 1972.
Cheers,
George
