RE:Massey 81s and 82s
I have wondered that very same thing as I have a 1946 81 that is a Row Crop. Only thing I have noticed that is different on tractors that are reported or said to Royal Canadian Air Force tractors are that they are all Standard treads.
That's all the knowledge I have on this subject, be interested in learning something new.
