Just looking through my copy of The book of the BSA Air Rifle, and wondered about the various foresight options they had available.
A quick look at a few of mine showed that most are the "normal" bead type, but I do have what I would assume is a Barleycorn style.

I was wondering how common are the others that are illustrated such as the Diamond, Blade or Buckhorn?

And does anyone have an ivory fronted version? I expect they were few and far between.

Of course there are the rear sight elements i haven't even got into looking at those yet such as the Curved Notch Backsight.

regards,

Lee
