Raleigh folder and UN72

I was able to get a hold of an NOS UN72 73mm shell with 113mm spindle. Stupid question though, given I'm more of a cup and cone than a cartridge guy. The left side shell slips off, the right doesn't appear to (maybe I haven't forced it adequately). What exactly am I supposed to do here? Does the right side cup with the shoulder come off?

Thanks for any help

On a UN72, both cups are removable. All the ones I've seen have black cups and a silver cartridge. It takes some force to get the right one off. I usually put in in a vise without clamping it so that the shoulder of the cup sits on the vise jaws and give it a whack with a wooden or rubber mallet.

On the UN73, the left cup is not removable.

Thanks cheq

I was a little paranoid forcing the right cup. Looking at it more closely, I can see where it's binding so I'll do the rubber mallet treatment tonight.
