Don't know M-number (M-3106?); don't know manufacturer (Lapp?). It measures 7½" tall, top is 10" wide, and the pinhole has a metal insert that appears to be 1½" in diameter. You can see the logo on the top umbrella and middle skirt. The only damage I can find is some surface scratching on the top where it sat on a shelf upside down for years. Cool mottled glaze that didn't take in a couple of spots. Asking $20 plus postage. Thanks for looking.
