The 1942 date, in my mind shows why they are rare. With industries turning to war materials, and so many things declared war usage for instance, aluminum, chrome, brass, I'm betting Lucite was in there too, with all those aircraft canopies to make. If you will look in the magazines like Mechanix Illustrated, wartime editions, you will find that common items like flashlight batteries, and most ammunition simply were not made during hostilities. Most of the 1942 model cars, had painted bumpers and hubcaps as chrome was pulled off the market, and even aluminum pistons were replaced with cast iron ones. Plastic handled Craftsman, geeez, another thing to watch for at swap meets! Love it.
