VTG I JMF I Sterling Trombone Horn Charm

In great condition, this is a very old sterling silver charm made by the J.M. Fisher, Co., in operation from the late1800s-1950s out of Attleboro, Mass. The charm is of what I *believe* is a trombone, but open to interpretation! The JMF (and STG for sterling) stamp is shown in photo 3. Measurements/size, photos 4-6. All angles of charm shown. The last photo is from the obituary in 1920 of John M. (Melatiah) Fisher, over 100 years ago!
