This is a very interesting silver (sterling) French Horn Pendant. There is a mark on the bale of the Horn. One looks like the French mark for sterling silver, and I don't recognize the other one. The measurements of the horn are , counting bale, a little over 1 inch and a half North to South, and 5/8 of an inch East to West. The chain is also sterling, and it has English silver Hallmarks. It is a nice weight chain, and it measures 22 inches long. The piece is circa 1910, and it weighs 15.71 grams.
