Usually you see a lot of Littlestown vises, but they are always the small ones, 10/15 lbs, but this is the much rarer large one, the 1st I have come across. It is 40lbs, 4-3/4" JAWS, dimensions: 14-1/4" long x 6" wide x 8-1/2" tall. The markings are: LITTLESTOWN HDWE & FDRY CO NEW YORK NY MADE IN USA NO. 450
THANKS FOR LOOKING! Check out the other vises I have for sale.
