I've looked at, and bought and sold, enough ladies legs calipers at this point that it is the unusual ones that I love--these wonderfully plump legs with very tiny heeled are just the sort that totally do it for me! 19th century, with a big fat pin that is just right for them.
3 3/8" t x 1 1/8" w when heels touching. Surface aging as evident, more pronounced in photos than in hand and all to the good in my opinion. The pin hold them tight, but they'll open wide with some pressure.
