Roger,
One thing you might try is this:
connect the rotor to a control box, and then push the 'brake' lever.
Listen closely to the 'noise' it makes.
If the sound appears to come from the BOTTOM of the lower housing, it
may be a HAM-M or similar family.
If the sound appears to come from the SIDE of the lower housing, it
might be a HAM-III, HAM-IV, or T2X, but I'm sure all the T2X rotor
housings have definite markings you can't confuse with the others.
NOW ... if you'd like to dispose of any of them, I'M INTERESTED!!
73,
Don
