This is another near new swivel base that fits the Kurt 6" vises. Probably an import but nice quality and in very nice condition. Center pin is 1" and the "T" slot is 7-1/2" diameter. I tried this on my kurt vise and it fit perfectly. You may have to put a new index line on the vise to match the base graduations. This is not the base that I just sold. It is another one.
I DO NOT MAKE SECOND CHANCE OFFERS.
