I’m good thanks mate I hope you are too, thanks for the info I wouldn’t of guessed the rear valve unscrews from the main part of the body so that’s a great help
The other thing I’m stuck with is the little silver pin that goes through the side lever cocking linkage into the main body tube it only sticks up around 5-6mm and can’t be tapped out as there is no hole underneath the body to put a punch in there I’ve tried gripping it wit pliers just to see if it turns do I could pull it out but no chance, I also need to remove this to get at the seals on the piston
Thanks a lot

Andy
