I bought my first '51' on a local flea-market yesterday (no idea how it got there, between all these Heros and WingSungs)
Not a 'proper' one, just a teal-colored Special, bought to see how this whole '51' thing works. The seller put it in a box together with many rust-covered, completely destroyed pens and I just HAD TO adopt it. It has one issue though - no clip nor jewel and the cap screw bushing looks like it's destroyed (I'm not sure, as this is the first '51' I had in my hands ever). Take a look at the picture below:

So, if anyone has a cap that is damaged and no longer needed, but these three parts are still re-usable, please share with me

Question to the experts out there:

Would the clip and jewel from Parker 61 cap fit?

OK, how about a whole cap? May have dings and dents, since I need only the clip and jewel to be intact.
