In the thread about Vert-a-Pack auto carriers, http://www.frisco.org/vb/showthread.php?5069-New-HO-ExactRail-Vert-A-Pac-Autorack&p=34970#post34970 wmrx mentioned, "Those canstock cars are pretty neat, too. I'd like to see a nice HO RTR version from one of the better manufacturers. Does anyone know if these cars ever came to or through Missouri?" There were a couple beverage can plants in the St. Louis area to make cans for a major customer there. One of these was Metal Container Corporation in Arnold, just off the Frisco River Line. Google Maps shows a spur line to the plant, so rail shipping and receiving was possible. Unfortunately, I do not recall how the metal came into the plants, but know that it looked like a big roll of paper. It was fed from the roll to a stamping press to make cups to feed the draw and iron can body forming process. Trucks generally hauled out the finished cans. Some of the aluminum came from Ravenswood, WV (hence the B&O connection) and from places in Kentucky. Some came from Alcan in Canada, too. I do not know whether Frisco had any Can Stock Cars. Roads with on-line rolling mills were more likely to have them. Were there any aluminum rolling mills in Frisco territory?
