I would say that it is a 29K. I don’t believe that the 29-4 ever had the adjuster for the take-up lever. I have two 29K70 machines, and one of them has had the Driving Lever replaced with a non-adjustable lever. It still works alright. That’s not a user adjustment. It was set at the factory. But a 29K70 originally had them.
Of course, I guess the machine shown by the OP could be a 29-4 with an upgraded Driving Lever....hmmmm
Also, I don’t believe that I’ve ever seen or heard of a 29-dash machine with any higher number than 29-4. Since the machine was modified considerably in the submodels after 4, I wonder if there were any of the upgraded models made in the USA? I hadn’t thought about it before, but now I’m curious....
