Lots of engraving going on here. Starts off with the big button on the dome along with PAT DEC.19.1871 on the crown. The front skirt has A / HEMINGRAY / No 4 and on the rear is 4 / PATENT / MAY 2 1893.
One drip mostly missing and a couple others with flakes gone but nothing to really detract from it. $25 plus actual shipping.
