Removing rear cell from 21mm Super Angulon f3.4

[x-ray]

I recently purchased a nice 21mm f3.4 Super Angulon and some of the black paint has flaked off inside between the front and rear cells where the diaphragm is located. It appears the rear grouping screws out of the focusing mount but I don't want to do something stupid and damage it if this is not the case.

Can anyone tell me how to remove that rear grouping? I don't want to disassemble the cell just remove ir from the mount as a total unit.

Thanks in advance,
Don

Don,

Check Ellen's post in today's active threads. One poster took apart his 21 SA and the VF'er. Lots of pics.

I did check it but it really didn't explain how to remove it. Thanks!

Tom A supplied the answer. It simply unscrews.

Thanks Tom!
