Small Sterling Clip/Pin

I found this clip/pin this summer. One of the main reasons for getting it is the way it goes with the large oval pin I already had (pic 3) The mark (F&B) seems to indicate a newer piece, but the combination clip/pin back looks older The enamel is really nicely done and it displays nicely with the lager pin. Note: the "discolored" ares is where I wiped out the price with a photo program. I like to keep a record of the stuff I get and the prices. Why the dealer put it on with a marker I cannot guess. Easier than a tag I guess!
