This old nail file is most likely from the early 20th Century. It has a steel nail file encased in a repousse sterling silver case with a floral pattern. The case is compressed for 1" of its length (see 4th picture) making what looks like seams along the side. This is the only damage. The file has a loop to attach a chain, perhaps as a key ring. The case is marked Sterling on both sides. It tests positive for sterling silver.
