Looking back through old threads, and anywhere else I can......I have found similar sights to this (fitted to an early standard no 2 "S" prefix)......but nothing that matches exactly.......put me out of my misery please someone, and let me know the model and number please!........thanks, Ed

In British slang an anorak is a person who has a very strong interest in niche subjects.

I agree with Garvin Ed, 21a. The sight fixed to the Post WW1 Standard was initially called the No22 and by the 1930s, simply became known as the BSA Aperture Sight, according to my 1937 Parker Hale Catalogue. The 21a was redesigned in the 1920s and had squared off shoulders rather than the rounded ones of the pre WW1 version.
Kind Regards,
John
