Yes, mine is a toolroom model with inclinable ram; mine is early wartime, with the nice paint finish, I think war finish started in 1943 over here. I have tool holders for the OK forged tools and the 6" vertical vise and adapted a dividing plate and sector crank so I can do dividing work as well as angular work. I am always surprised anew at how sensitive the feeds are; dial a thou, and it moves a thou. I think the basic design of it goes back to at least the early 1920s I saw an early picture of one that was driven from overhead, but still had the geared speed change arrangement of the later ones like mine. I also had a P&W #3 jig borer, which was given to me, it was handy for many jobs due to its capacity and ridgidity; the fellow who bought my business junked it --- sad!
