From images, is that a "scope rail" running length of Spring tube from trigger block to breech ?
Tried to expand photos, to no success.
Previous owners mod? Personally in my limited experience not heard of or seen scope rail on aCadet or Cadet Major.
Target model to take Diopter sight?
pix are working in that gallery now
That scope rail looks decidedly non-original... but if it works, I'd leave it alone.
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
Yep photo's are fine, well done.
Thanks to all who replied and helped ID the gun as a Cadet. (btw I dont intend to do anything about the scope rail)
