Mr. Terry, good to hear you're doing well. And it appears you are still hooked on odd vises!
Mr. Kyle, the wood assembly bench reminded me of my B-I-L. Sometimes he gets taken at auction, and sometimes he scores. He won (2) 8' x 8' heavy duty shop assembly tables, with similar vises mounted on each side of the table from a school surplus sale, barely used...$50 total...sight unseen. They are working out great in his shop.
They look much like the one in your last photo. Now you've got me wondering about the vise brand...
