Just purchased an Ansonia Ogee at auction . Had to be completely redone. Has a red bird or looks to be a scarlet tanager on the reverse tablet with gold and prussian blue background.All glass original. The bod that came with it a a plain brass and about 1 1/2" in diameter. I noticed some very ,perfectly , engraved #'s around the outside border on the front edge of the bob. They are;090-20-3540..Looks like a social security # to me! Perhaps someone's idea of owner identification? Have never seen this before..Any ideas--The same # is written in pencil on the back board of the case but I find nit no where's else..
