How do you remove the neck ring and swivel from the head on this Westinghouse?

I have the fan apart but I can not seem to figure out how to remove the neck from the head. I removed the set screw in the collar and it turns a bit but I can not seem to figure it out. This is not my fan but its the same one only a 16 inch.

There is a snap ring (or something similar) on the base of the inside of the motor head. Let me know if you still need help, and I can probably provide pictures.

I have a 16” and 12” model PowerAire. I never figured it out. If you do please post photos. My 16” is a garage fan. My wife bought it in 1985 for $4.50. It sat unrestored until about 6 years ago. It a quiet fan and one of my favorites. Just because it works flawlessly 👍
