I had these listed as part of a set of four 19th century ladies legs calipers I purchased together, but perhaps no one needs a collection of four, so I've decided to list them individually. Made of steel, likely by a metalworker or machinist for their own use, these are the smallest and I think my favorite of the lot, due largely to the wonderfully balletic shape of those bare feet! 

2 1/2 inches long and in very good shape, useful as both inside and outside calipers, with the pin nice and tight, but opening easily with some pressure. Wear and some darkening/rusting to the surface of the steel as evident, though it believe these would likely polish up some if desired.
