Dear all, I won a HO scale Sand & gravel Hopper on Ebay--part number H-301. It is made by Roundhouse Products. The box is blue & yellow w/Diecasting Co. Los Angeles,Calif. on the box also. I know this was made in the 50's or 60's. The SSW hopper is all metal w/operating hopper doors and even metal horn hook couplers. My question is, is there a place or book to find out when an particular item was made, year specific? I know in 1973 Roundhouse came out w/Sand & gravel cars in Styrene and in the
1950s they moved to the Anza Ave. address in LA, but I was wondering what yr. this car was released. Thank you in advance everyone. jaijef- posted
