Looking for a set or single numbered 30 endlink for my Wittnauer professional bracelet. Looks like below:

 

I know this is essentially hen's teeth. Any help is appreciated!

Anyone?

 

Would Longines have had a similar bracelet or endlink numbering system?
Not that the supply of vintage Longines endlinks is any greater than Wittnauer...

 

I'm not sure, as you say, neither are in great supply. From my searching I haven't seen a longines with the same polished center BoR link.
