3.  What is the  difference in the Ham series of rotors?
The Ham-M rotor was released in 1957, and there were 5 series with the last 
rotor being produced in 1973.  The Ham-M rotor would have the series 
number, 1 - 5, followed by 3 digits which indicated the week and year of 
manufacture.  For example, a rotor with the series number 5 322 would be a 
Ham-M, series 5, manufactured in the twenty-second week (the '22' in '322') 
of the year 1973 (the '3' in '322').

Hope this helps.
