1940's Rare Vintage Sandor Cuff Bracelet with Lucite

Vintage spring-hinged bracelet by Sandor. Sandor was in business from 1938-1972. The patent number is for the spring hinge mechanism, filed for in 1934. Brass, big statement pieces and lucite were popular in jewelry design in the 1940's. Most likely this piece was made during that time. "Sandor Co" was stamped on pieces after 1955. This bracelet has the pre-1955 "Sandor". There is signs of wear and discoloration. I did not attempt to polish as this is a collector's piece. I am NOT an expert on Sandor jewelry. The hinge mechanism works without issues.
