In that case Rich, will email you - thanks
Caisterboy, the current arrangent is an o-ring. I want to ditch it and replace it with a "parachute" type washer, as these are more efficient and seal better. The crap sealing of the o-ring design is why BSA need to have a "buffer washer" bedind the piston head, to soak up the impact of the piston slamming into the end of the cylinder

Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
