1978 Skeet model.
Puchased unseen I expected a scrapper but it turns out to be a sleeper.
Shot it for the first time on Wednesday and although it shot the punchy loads OK I was a bit dissapointed with its light load performance.
Gave it a full strip today and found 2 things of note. The feed latch fell out and the piston was upside down

Luckily I found some old advice on another forum by 'Virginian' ( My Hero! ) on how to reattach the feed latch , which is now glued and clamped.
The white butt pad spacer had disintegrated and a new recoil spring is on the way.
Having owned a 1100 in the past I feel a bit silly missing the piston issue.
Anyway should be 100% pretty soon and I must say I am very impressed with the amount of knowledge that can be gleaned from this forum.
Next time something else falls off I will be in touch.
Thank you Rob.
