Here are pictures of small early MT tag (like yours) and late large MTA tag for you to compair with. It certainly looks as though the A may have been added in later on your tractor? In my old hand written files somewhere I have an MM manual that has a bit of info on this change over from MT to MTA.Īs best I recall, it said something about the last few MTs with KE engine would now be refered to as KEA.? Spoked wheels for rubber tires from French & Hect were available and soon enough the cast center with rim was produced. The bigger plate was now stamped MTA and engine tag said KEA. heads, oil bath air cleaner, and a new serial number plate that was larger and had a big MM in the background of the whole plate. MM claimed this tractor as their own and went about up-dating them with high comp. Most of the early MTs did have the TC on the radiator and not the MM. It was merely assembled and sold by MM after the 1929 merger took place. This machine is a Twin City design and was not engineered by MM.

The small tags said Twin City Tractor and was stamped MT. In general the early MT was a steel wheeled low compression tractor with a dry type air cleaner and small serial number plate like yours has. I would call this low production, but selling prices here in the states do not generally reflect my opinion. The serial number list on my website came from the archives and has proven very reliable over the years. The tractor you have taken in has been up-dated to an MTA.
