Ray did you wright all that or is it on a PC file?
Service Bulletin #3 that I have states the Ridemaster Strarted in June of 1948...
I wrote it out Jerome.
However, the copy of the engineering changes that I have shows the first engineering change at 4/15/48 ?
It shows the front wheel size being changed from 18 inch to 16 inch at 6/23/48 ?
I have no idea if any of that is correct or not but I would think that it is very possible that the engineering change could be dated for April and the tractor not actually produced until June.
I do know one thing that is for sure and that is that I gave up a long time ago in trying to make sense of the information that is available on these tractors !
It's really too bad that this Ridemaster does not have the original engine.
The engine serial number would sure clear up some of the questions that we have on these tractors.
