Possible English made general’s star with “T” bar pin.
Note; I have found a J.R. Gaunt, London 1st Lieutenant’s Bar, of the coffin shaped type with wide border, with this same “T” bar pin. I think it is WWI-30’s era, and may even be WWII period. This general’s star could very well be English made. I have added photos of the Lt’s bar for comparison.
I have concluded to describe this Sterling marked star as a jeweler made piece circa 1920’s perhaps later. This came from a recent auction; insignia from the Richard Gimbel (of the Gimbel’s Department Store family, and WWII pilot); not Gimbel’s but something acquired by him.
Although one is marked sterling, and 2mm larger, I believe they may have been made by the same maker, having come from one collection, represented by these two piece alone.
The star measures 24mm point to point. There is no hallmark.
Excellent condition. A great variant!
