Air Arms Optics?

[Longdog]

Mounted on my BSA mk2 s Airsporter is a 4×40 Air Arms scope,with the remove cap,use coin windage adjustment and a 'sniper' style elavation turret.It looks to be of the period of the gun its on,so my guess is mid 80s.Dose anyone know if AA had glassware made for them in the early years or is it just a brand name?.My historical knowledge of these things is very limited,so any help would be appreciated.ĺ

Would have been made for them, BSA also had a branded scope too. Grinding lenses is a whole other art .
