Can you identify this bracelet end link similar to a 172?

I received a vintage Omega 1171 bracelet recently but with the wrong end links. Someone has removed the originals and attached the ones shown on the left in these photos. On the right is a 1162 bracelet with 172 end links. They both have the same 21.7mm width but the replacement link has a smaller attaching link segment measuring between 8.0-8.5mm wide as best I can measure. Spacers were meticulously made out of wire to make the links fit. The replacement also has 4 parallel grooves cut into the links center portion whereas the 172 is plain. They both have the same brushed finish. It does seem to be an Omega link.

Can anyone identify this end link?
