It looks very much like a Keller, especially the vise jaws and rails, pulley guards, and saw frame. As to model I can’t right off the bat but I have some older Keller literature I may be able to scare up and check. There isn’t much from the factory or manufacturer on them although there’s plenty of the actual machines out there. Here’s mine — a model 3WA — which came with coolant and air over hydraulic downfeed. I’ve done a few modifications (new guards, oiling cups, etc) as it was a real basket case when I got it. Still a bit of one, but works and I use it for larger stock.
