Looks like a Multico K, but an unusual one in that it looks like it’s weldment construction as opposed to cast iron for the frame. There’s a few things that look different to a Multico K, like the table and hand wheels look completely different, which makes you wonder whether it’s a Multico column and head on a different morticer’s base? The Multico M morticers were made by weldment, but perhaps this was a very late K before they went over to the M.
