Earl,
Ok, I have a little better understanding of the “heavy duty” reference now. As you mentioned, the changer machines use the heavy duty Type 3 motor. And... I indicated that the Type 3 type of motor (though with a shorter spindle) is seen on other non-changer machines (8-30, 8-60, 12-25, etc) using the same coils, as well as indicating the Type 2, same style motor, is a 25 Hz motor using different coils. What I have come to realize today is that there is the light duty (going by appearances) called a Type 1 motor which also is also used on some non-changer machines (7-26, RE-45, RE-75, etc). The coils are only slightly different in appearance and do measure different than the Type 3. I get 2.5 ohms in the uppers and 152 ohms in the lowers. I’m sure you have come across these two types of motors, but I’ve included a photo showing them below. Also added the page from the RCA Victor Data Book due to pertinence. I do like that the Type 1 style protects more of the motor’s disk, that’s a very good thing.
