Omega BOR 555 End Link(s)

I recently picked up a nice Constellation 168.016 full set at auction with it's original 7 row BOR bracelet (1068) as well as later edition Omega Leather strap with omega buckle. Unfortunately the bracelet has a missing end link hence I'm on the hunt for a S/S 555 (19mm) end piece so I can reunite Bracelet and Watch. Happy to buy a pair if that's easier/preferable for someone. Doesn't have to be pristine condition.

Let me know if you can help. Purchase photos below just for info.
