f.w. Stewart was a gadget company.
I have a collection of popular mechanics from the 30's through the 50's and stewart was an advertiser in that rag for all sorts of stuff. Things for the shop, hobbyist, income potential tools for the mechanically inclined, and automobile owners. Some of their automotive products looked top notch; they had some really trick looking speedometers for 30's vintage vehicles.
I bet it would bring some bucks at a swap meet.
changes fer shure.
One issue of pm from the 50's(56?) had a feature article on die cast small, lawn mower size, 2 cycle engines. It's closing statement was they had a promising future for all sorts of engine powered products; oh yeah and don't forget the turbine powered cars and trucks. I only saw "one", the bat mobile.![]()
