That's mine
Which for a short period behaved itself
But now leaks between the barrel and tube where you can see the silver coloured bit joining.
Even when working it seems to be designed for very short pellets more like the slugs we had as kids.

I had a lot of fun yesterday firing the 2620 and loading in 22 balls through its gravity feed magazine. It is a very accurate pistol with a lot of pop. Your comments on reliability make me question whether I should just put it away as a rare collectible or just enjoy it. Always the question with CO2’s especially for me. Think I’ll ask my trusted repair guy his experience sealing these. Part of the joy of collecting is shooting them. The genius of Crosman was simplicity and thus easier reseal.

Asking Baz if he has Schimels is a bear in the woods question
I believe the Schimel GP-22 was the first commercially produced pistol to use self contained CO2 capsules as the power source. It's a pity there wasn't sufficient time during the relatively short production period to fully develop the design. One of the main issues for the first time user is to forget to push the little reset button forward both on initial charging and prior to operating the charging lever for each subsequent shot resulting in the complete discharge of the CO2 capsule. It would have been nice to have had some sort of linkage between the charging lever and the reset catch to prevent this happening. The early production materials were also a bit fragile, but still rugged enough for regular use with reasonable care. I came across this leaflet suggesting that an air powered variant (AP-22) was made available, but have never seen or heard of an actual example coming to light in the UK anyway.
I have a nice boxed GP-22 which shoots well and provides a nice Luger like action to open the breech and insert the pellet.
Every home should have one.

After the circlip is removed deep down the tube of the single shot Rocket, you can be lucky and get the valve to slide out with a knock. The problem is removing the O ring right at the far end of the tube as it is usually stuck fast and gummy. Lawrie uses an aluminium tube with a saw tooth edge to clean out the old O ring. Apparently in the early days Benjamin supplied you with two O rings for the cylinder cap as the material they used expanded with exposure to the CO2 gas and you could not screw the cap back in after fitting a new capsule. They instructed you to fit a new O ring and put the old one to one side until it returned to size after evaporation of the gas so it could be reused. We think the wrong quality O ring was also used for the very back seal which causes it to get all gummy over time.
The Schimel is not a difficult pistol to re-seal. People make a couple of mistakes in assembly which cause them to leak. The chamber cup seals are the same in all of them but there are 4 design differences in the capsule valve unit.

I have resealed many Schimels over the years, I did one just last week, they are very easy to do if you you know how, and like Baz said there are 2 seals that are standard, but I have to make one or the internal seals, other than that no problem, I have had a couple of mishaps due to the fragile metal that was used in the manufacture, but when working they are great pistols.
Cheers,
Lawrie.
I'd just like to point out that there have been some great illustrated articles dealing with the service of CO2 pistols in AIRGUN HOBBYIST magazine.
I traded my Schimels to Baz
He understands them
To be honest I found them a bit scary
I had one that fired as you compressed the lever
I prefer the Challenger Arms Plainsman which is a straightforward Big Bang Classic pistol.
