Okay. Here's a question for you U-Frame knowledgeable folks. What were the primary changes from the 12-20 to the Pacemaker?
My 1936 Pacemaker was the 129th one built per it's serial number (107129). A couple of people have commented that it has some 12-20 features, perhaps carried-over inventory? In particular, the drawbar set-up, which has wider drawbar with less thickness than what I generally see on Pacemaker's. (Which, by the way, on my tractor is broken-off just behind the support - a good indication that it needed to be thicker metal!)
Here is a photo of my Pacemaker in its mostly original glory. Comparing it to the 12-20 above, I can see that the radiator top casting is different, both in the size of the riveted-on Massey-Harris name plate, and in the radiator cap.
What are other key differences between the 12-20 and unstyled Pacemaker?
