Sheaffer Triumph Feed Broken And Collar Stuck In Section

[spaceink]

Hello,

I'm seeing if anyone has tackled this problem. As I was trying to wrestle a Sheaffer Triumph nib off a vac filler, the feed snapped. The nib and the rest of it is out, but there's a length of the feed still stuck in the collar. I've tried to soak it and twist it out (It'd be nice to preserve the collar for a spare, just in case) but it's not really budging.

 

I do have a spare nib/feed/collar combo from a past botched vac fill project, and am hoping to at least get the collar out, so I can replace the Triumph nib unit and get this pen working.

 

Am planning to drill into the feed, see if it holds, and then twist out the collar. If not, I will possibly just drill out the feed and then use a larger drill bit to then twist out the emptied collar. Thoughts?
