This wooden hat tool is in excellent working condition. It has a metal screw handle for adjusting. The metal guide rods on the sides are calibrated for measuring. One side has numbers from with 1/8 wide divisions from 6 7/8 – 7 ¾. The other side has 3/8 divisions from 21 5/8 – 24 3/8 ( I finally determined that this measurement is the circumference). The patina is very nice. The piece is 6 ½ in. wide x 7 ¼ in. long closed. It is 2 3/8 in. tall at the ends.
