This week i bought 2 Gem air rifles which i want to get working again.
They are both 6.5mm bores and seem to be made by Jean Marck S.A.
As you can see one of them has been welded, so i first needed to remove that to take him apart:
They both have a machined piston without a leather seal (which kind of surprised me, but it seemed to occure often as i read on this forum):
One had a relatively "small" spring, but i think that the bottom one is the original spring since the upper one doesn't fit that well inside the piston:
Dave is going to make a sealkit for me! So i'll keep you posted on the progress.. It's not going to fully restore them because i really like the worn old looks of them.
