Enclosed are 6 photos annotated on the rear of each and comments concerning an interesting piece of memorabilia. The item was recently acquired by a friend from a gentlemen who stated it belonged to a now deceased party who claimed to have used it to work on Thompsons.
The cast vise accommodates the 21 or 28 Thompson with the butt stock removed. It was bead blasted and painted a color found in one of its crevices. Cast on the side are V-500 THE THOMPSON VISE PATENTED. The word patented is on a riveted rectangular oval. There are no other markings. It stands 7 inches high and 23 inches long, with 4 mounting points intended for bench mounting. Mounting points are 3 1/4 inches wide edge to edge and 16 1/2 inches center to center. As you read the lettering, the left clamp must extend over an edge as it opens vertically. It is 2 1/4 inches wide and with a 1/4 inch step it opens to 1 5/8 or 1 7/8 inches. It has a length of 1 inch with a 1/4 inch overlap. The hand wheel is removable. The right clamp opens horizontally 2 inches, is 1 3/4 inches deep, and 2 1/2 inches long.
