I have a Standard pre-Monarch that is in real nice original condition. The serial number is 42371. As far as electric starting systems without a charging system go, we have to remember that the factory starting system on a Gravely Tee Head engine had no charging system, and they used this through 1976.
That's interesting, Cliff. I don't think I've ever seen a pre-Monarch with a 5 digit number. Any chance of getting a pic of the tag?
I did find out the number of the other tractor with this style of wheel has a serial number of 3278 so it isn't far off this one. There have been a few of us that have tried some different theories about dating the early numbers but in my opinion they don't fit every instance and these early tractors are one of them. A 5 digit serial on a pre-Monarch would really throw a monkey wrench into the latest one!
