Dr.

You will be pleased to know that Bryan Smith, along with info from Ed Mills, has already done this for a number of Model Tractors.

I've been somewhat aware that there has been an attempt at this before. If you look at that "assumption" chart, his chassis number age of 207288 doesn't match the engine number age of 81751. I felt this particular chassis/engine combo is legit and is exactly how the tractor was built. EDIT: I've just now checked my own 1957 WD-45 chassis at 232994 and the engine is 45-94197-G. Both check out to be early 1957. I'm thinking March at 300 tractors per week build rate.
