My experience dates from the late 1950's, and the products were in bas relief on 1/4" thick alu sheets, sometimes with sand molded pipes stuck in for sprue's etc. Corn planter seed plates, gear cases for Maytag Washing machines, that sort of thing. Some of the stuff we made wasn't easily ID'd as to what part of a machine it may be for. And we didn't have time to ask any in depth questions when you are doing enough a day to be on piecework pay.
