Aristo-Craft Rolling Stock Versions This page is just some notes on different versions of Aristo rolling stock. I started it for myself, so as to be able to tell if I purchased (or about to purchase) an older version of something. Many times improvements are made, and the older versions are "blown out" at attractive prices, with no mention that they are the older version. Misc rolling stock Seems the changes in trim details is the same in various rolling stock, i.e. grab irons, etc is now blackened or painted. Not all rolling stock have a manufacturer's mark (with year of manufacture), but many do, can be on the side of the car or on the bulkhead.
