Wasp Vacuum-Fill (Addipoint) Clip Removal?

[Gutbucketeer]

I just received a Wasp Vacuum-Fill Addipoint pen that turns out to have a broken ring clip. Pictures are shown below.

Before I destroy the cap trying to remove the broken clip. Can anyone help with the following:

 

1. Is the jewel on this pen friction fit, or threaded? Can I just carefully pry it off? Was it glued?

2. How is the clip removed? Do I have to remove the inner cap, or just the jewel to removed it?

3. Do you know a good source for a replacement?

 

Thanks ahead of time.

Took a risk, and found that it is friction fit. I pried it off.
