Something else I wonder about, if a particular model is produced and available, say from June 1940 to March or April 1941 for the '41 model year, how far into the model year do the revisions inherent in the change from say code 121 to 122 occur? I imagine it's partially dependent on any particular model. Also, what generates the changes? Just a matter of curiosity.
