Thanks Drew
That's great, the one I've acquired is 1978, and that also explains the sights, 40 years ago I obviously took out the adjustable and used a ring, so she was right! I've checked on Chambers and they are no longer available, so any out there have a 75 foresight element ideally 4.6, but any ring will do as I can ream it.
Or even one they can lend me, so I can make one the same profile?
Checked on the picture of the original and no black inserts, we know it was a 1977, looks like the black was not on the first year ones.
