A foundry is a very expensive thing to set up, and most manufacturers find it more cost-effective to leave that sort of work to specialists. As far as I can tell, "Qualcast" began as a contract foundry, and did a large business providing grey iron castings to other companies.
Good point. The company was originally known as the Derwent Foundry which supplied cast iron components to industry, notably cylinder blocks for car engines. During WW2 they obtained the exclusive UK rights to an American ferrous diecasting process for ammunition manufacture, and after 1945 this process was also used in the manufacture of components for the motor industry.
As to the speed the motor runs, this has yet to be determined as all is not well with it. There is excessive end float on the spindle, suggesting a problem at the base. A ball bearing missing perhaps?
The idea of a shop window display had not occurred to me, but it could be the answer. Watch this space......
