Antique Large 40lb Swivel Base Vise J.S.&CO. NY NO.1 Pat. June 9:91 -4” Jaws. Condition is Used. Shipped with USPS Priority Mail to the United States only and combine shipping. Please look at pictures this is the piece you will receive. Made to blot thought a table the swivel base is locked by tightening the nut under table. I have seen some that have a large wing nut to tighten. The base is screwed down to the table with 6 screws not supplied. The base is around 6x7/16 inches. T...he treaded rod fastens to under side of vise and a hole must be made in table to be blotted to. The rod is around 11/16 inches thick. The jaws are around 4” wide 1-1/16” deep. Jaws are in good shape and close tight. One lower corner edge of jaws has a small piece missing. Please see pictures. It works very good. The jaws open more than 7 inches wide. I would say that is around the biggest piece that would fit. I have had it over 40 years and it was old than. So I am assuming the patient date was 1891. It is around 4-1/8 inches from the top of jaws deep. I will be shipping the vise in piece, like it is pictured in #11&12. Any questions please ask
