Knock Kneed Antique 5 Inch Machinist Made Ladies Leg Calipers Monogrammed EJGI've bought and sold a good handful of ladies legs calipers over the years, but don't believe I've ever seen a knock kneed pair! So fun. And with a satisfying negative space created when the toes are touching, it feels like these calipers are happiest closed the most modest of ladies legs! Made by a metalworker or machinist, who stamped their initials, EJG near the top of one leg. C. late 19th century I believe. 5" t x 2 1 4" w when toes are touching.
