Got these at an estate sale and the guy had many vintage car parts and many vintage cars back to Model Ts. Was wondering if these came off an old auto from long ago. They measure about 4 inches across. Thanks for any info.
I would say these center/grease caps probably could very possibly been from the Royal fleet of State cars of King George V,VI. most of the older cars have been auctioned off over the years and some have been in the United States. I am sure some of them had restoration work done to them so these caps may been sold during that process.
Daimler,Rolls Royce and Bentley was some of their favorites to use, but others were in the fleet as well.
