Parker Vac blind cap jewel and tassie

[da vinci]

I have 2 Parker Vacs which I would like to restore, however they are missing the tassies and the jewels from the blind caps (but perhaps unusually they still have the complete clip/jewel on the cap?). I have attached a picture. You will note that they are different models of vac. The smaller one has a lockdown filler, the larger one a speed line filler. I am not entirely sure which models these pens are. Both have some barrel transparency.

I was trying to find a source to buy the tassies and jewels with no joy despite the wealth of websites/ebay sellers offering spare Parker parts. I would be wiling as a last resort to use m modern reproduction parts should such a thing exist.

I would be grateful if anyone knows of a source for these parts that they send me a message or post here to let me know where I might acquire them.

Thanks.
