The Silver Squirrel has dated this piece to the 1900s.
I do not know what it was for. It is in good condition being free from splits, holes, repairs, and significant dings, there are a couple of small dimples, see final photo. The inside is clean and gilded. It measures approx. 2.5 inches (6.6cms) tall by 1.5 inches (3.7cms) wide and weighs 36 grams. A very interesting piece.
