Sorry, don't have a drawing for the Hatsan Sniper "pickle" but I have taken a few apart. It was difficult because the front disk snaps in place and where you might "think" the snap features are is 90 degrees from where they REALLY are!Once you can remove the front disk the spacers & hair-curlers & felt pads assembly will come right out. DEEP in the pickle (jokes abound) you will see a nut that is threaded onto the end of the barrel. Loosen and remove that nut and the pickle will separate from the barrel. I haven't needed to go that far yet and dread trying it because i think getting the pickle's front sight back to dead center "may" be a painful and long trial & error process if there is no alignment detail (notch?). Good luck with that.Parts are SIMILAR to QE parts, see attached.I am working on a refurb Mod85 Sniper now and will try to post some pickle disassembly instructions and photos that may help you.
Holy moly, I can't find where I read it or who posted it but they did a bunch of shooting with their hatsan 125 and stated that they cocked it using their left arm. Well, so far I've only been trying to cock mine with my left I thought, hey lets try my right and dang if wasn't able to cock it 1 armed with my right 👍 Then I thought about it and I always cock my Diana 48 with my right and use to pump up my Aspen with my right at last the dim light bulb went on. Use your right arm dummy! 🤔😁
