“Strange”? It’s just a spark plug socket.
Is it an LT28? It looks pretty typical of their 3/8dr sockets from the 1940s. Their first CV sockets (1/2dr) had “Chrome (CV) Vanadium” stamped in italics under the roman “BONNEY”. “Made in USA” was off to the right of that. My guess is, removing the “Chrome (CV) Vanadium” and placing “Made (CV) in USA” in its stead indicates wartime alloy restrictions production.
The flatware is probably WWII. Skimming
this article, seems like manufacturers sometimes had difficulty adapting to revised specs. The hole in the handle was specified in 1926, but not put into production until 1941. If yours is really brass-nickel, perhaps it was one of the few modified after 1934. The article has what I think may be an error, stating WWI material was tin-plated steel. Tin-plated steel was instituted in 1941. Silver-plated steel in 1943. Stainless was instituted in Aug1944.
Check the spoon with a magnet. Stainless or nickel should have only the slightest pull, while steel should be strong. I don’t know what to think about the verdigris corrosion, could be transferred from something it was in contact with, rather than the base metal.
to go seek out sales in my area. I found one in the next town over, scored a South Bend 9" lathe for $150, and was hooked. Most everything I know about vintage tools and brands, I learned from all of the posters, past and present, on this thread and it's many spin-offs. I even started a thread on double box end wrenches that I'd gathered from sales, and it became a top ten thread in the Vintage Tools section.
