I worked in an automotive electrical parts plant. We made starting motors, alternators, coils, points, condensers, sparkplugs, and 2.75" rocket warheads. Vietnam era. Theft of the auto parts, particularly sparkplugs, was an ongoing aggravation for the company. I considered pitching a couple of reject warheads (we had lots, serious problems with QC on the threads on the base which screwed into the motor) over the fence at night to make a pair of endtable lamps, but never did.
There were also Inglis pistols assembled from parts long after the war. I can remember frames for $10, $15 with the stock slot.
