I believe this to be a U-272, although its measurements (3 ¼" x 3 5/8") make it too short. The profile doesn't match anything else with those exact measurements, however. Also, the Price Guide lists the Caramel N-N U-272 with a "flat inner skirt." I'm fairly sure this ain't that. So, whatever the U-number, it's pretty crude, and it's mint with a clearly carved MLOD and variable, mottled glaze that looks even better in hand. Asking $17 plus postage.
