If there is a genuine possibility of corrosion, try soaking the ejector (using an eyedropper) with CLR (although I personally prefer
phosphoric acid; it's milder). Citric acid can work, too. Just beware of one thing, any acid can neutralize/remove Bluing.
Then find a steel punch and
lightly tap the ejector in. This should break it loose without doing mayhem to the ejector; it may be retrievable. Also, check for a cross pin in the bolt head that may be retaining the ejector. It will need to be driven out to permit removal.
My experience with ejectors has repeatedly tracked down to a ruined ejector spring, and I also find that many ejectors are retained by a cross pin. Often, removing the cross pin will free things up so the ejector can be extracted. In all such cases, I have also generally found that some sort of pressure excursion has jammed the ejector, destroying the spring, causing the problem in the first place. No need to ask me how I know this. Check your loads for excessive charges.
Don't discount magnets. A Neodymium magnet might extract the ejector once it's loose when other methods have failed.
If the spring is trapped, take a small (tiny?) self tapping screw, remove the head, chuck it in a pin vise, and use the screw to engage and extract the ruined spring.
Once out, clean the extractor with steel wool, and soak it in CLR to remove any seed rust. Once clean, rinse it liberally, then apply a
reliable bluing agent; and try reassembly. Lube it well with a grease lube made for guns. You will probably find that you can rescue the ejector, but it's the ejector spring that needs replacement. Don't get excited if you can't find the perfectly correct spring, as ejectors can be tuned by replacing springs.
Just a few ideas that I learned scores of years back when training with IBM as an Electric Typewriter Repairman. If all else fails, and you can get the extractor out, get the dimensions and see if you can make a functioning duplicate. Materials hardness is important here. We were actually fabricating parts for Typewriters which were older than we were, and were out of manufacture for decades. I was in the last class (1968) that dealt with these issues. We were taught to recover the ones we couldn't fix, and cannibalize them. Often, our next raise depended on that ability. The IBM Model 72 Selectric (Golf Ball Typing Element) had just been released.
