This was with a box of accessories for a lathe I recently bought. I would like to know who made it, so I might acquire the vise that goes with it. It’s base is 4-5/8” x 7” and is 1-3/8” tall. The outer vernier diameter is 3-3/4” and the center through diameter is 2-5/8”. The machined bottom key slots are 5/8” wide. Any help identifying would be greatly appreciated. Thanks in advance.
