Right out of the late 1800's to early 1900's. PURCHASED AT AN ESTATE SALE.
Made of brass and porcelain. No markings found. The perfect amount of patina including worn brass and light crazing.
Approximately 2 1/4" tall and 1 7/8" wide.
The pin on the back still works perfect after all these years.
Let me know if you have further questions.
