Well with the help of a chap from the range we took the Airsporter apart this evening and to be honest it was going very well and everything is surprisingly well lubed with the factory grease still and minimal wear until we got to the piston head.
The leather piston ring was mashed to pieces and embedded within the leather were in total 4 metal .22 darts from something like a Gat with plastic rears mashed into the leather. it would seem my braincell devoid cousin when he had his hands on this has tried feeding darts into it and has somehow managed to get them to go backwards into the piston head which had then forced them and compressed them into the leather. Luckily there is no damage to the metal part of the head or the piston casing, but needless to say i've already sent the warning via my father than my cousin is under no circumstances to come anywhere near me unless he wants to lose a few teeth,
The Airsporter was never his to mess about with and on top of him knackering the bluing we then find this I'm not a happy camper.
Aside from that all it appears to need is a new spring as the current one is buckled (replacing for a comparable spring not upscaling) a new leather piston washer and an overall clean, re-greasing, stock tidying up and re bluing and all is good. So not as bad as thought.
Gave part of the stock a 5 minute work over with Meths and 0000 wire wool to see how it would come up and you can see it below.
