It appears that the factory may have had a code system at a couple of times, but it soon became so cluttered that it then became meaningless.
It also appears that there was some effort to incorporate HP as the first number with the year as the second in this model code after 1979. And a last number of 2 being a standard shaft, with a 3 being longshaft.
You may also see duplicate model numbers (like the 6002 & 6003) & maybe for the same hp of motors, but usually there are considerable number of years difference in manufacture (like 30+) so identification is easier.
