Thats an older Schiller Pk, C-series and Wilton did not make a 8" C-series. The biggest they made was the C-3 with 6" jaws. I don't know, I certainly am not going to ask him to remeasure the jaw width. The giveway is the smaller anvil surface and deeper throat. No way thats a 1780A..Notice, the jaws bolt up from in back. Thats a C-3, 6" Combo..Still, a great buy! I might be wrong as I usually am, but I think that vise might be missing the pipe jaws. Pipe jaws on a C-3 are $100+ I think. Oh, and another thing,he might have been researching red Wilton combos, not bullets, and came up with that 30,000 psi. Thats what their import utility vises are rated at. That C-3 is 60,000.
