Vintage MCM Silver Double Cuff For Arm Or Shoulder

Wonder Woman does Studio 54! I'm not great at valuating jewelry, but I snatched this up an estate sale without blinking! The metal is strong--it could be stainless steel--it does bend slightly at the openings, and because it's not tapered, I have my suspicions it might have been an upper shoulder cuff. On the wrist, its boss lady punk, but with a throwback shape that seems MCM or even Art Deco. It has the normal scuffing and scratches of any metal that's been used to deflect evil or bullets, but it measures 5 inches in length, and the cuffs are joined with equally sturdy metal. As mentioned, can be shaped slightly to accommodate smaller wrists or larger forearms. I need to go back to college and study metallurgy!
