New-Old-Stock Omega No.6 End links 19mm Speedmaster

I have for sale one pair of genuine Omega no.6 NOS/unused end pieces in 19mm to fit flat-link bracelets and straight-lug Speedmaster, Seamaster 300 and Railmaster watches.
100% genuine and original parts, not reproduction ones. Excellent unused condition with perhaps light storage marks from 50 years of storage. Never fitted to a watch.
I find pricing of such rare parts difficult but think around £1,500 gbp to be fair. I will post worldwide included. I will also consider swaps for Omega parts or watches.
Many thanks.

This pair sold very quickly so I have decided to sell two more pairs of my remaining stock.
100% genuine new-old-stock, unused No.6 19mm end pieces.
Many thanks

Sold. Thank you buyers and OF,
