Welcome to the Forum, you have a wonderful example of the .22 kit gun, in the somewhat scarce 2" barrel. If it was mine, I would be tempted to not shot it, which would be a shame, as they are great fun shooters. If you do shoot it and have any problems with shells extracting from the chambers, it is common. These guns seem to prefer standard velocity ammo. Polishing the chambers with a bronze brush wrapped in bronze wool (0000) has helped quite a few. Many have had the chambers reamed with a Manson SAAMI standard finishing reamer which usually cures the problem.
