This little bisque leg measures 2 and 1/8" long from the top of the thigh to the bottom of the heel. The inside of the leg is marked at the top with the number 210 and a double digit number that I can't read which is on the opposite side.
The condition is very good. There is some wear to the black shoe on the outside edge and there are numerous kiln specs on the leg. There is also a spot on the inner thigh that appears to be slightly glazed which is odd, but that's what it looks like.
I purchased this leg in a lot of doll parts thinking to use it to fix an all bisque Kestner that has a broken foot, but it wasn't the right size to work for my doll, but maybe it will be just perfect for your doll.
