maybe broken firing pin ?????????
It will be marked on the barrel.
They were made in several calibers- will be marked on the barrel.
Should be marked on the barrel. If not, take it to a gunsmith.
caliber and maker's name
The Slavia 622 is a .22 caliber pellet rifle not a .177 caliber rifle. It is a single shot Break barrel rifle. The rifle is a spring piston shooting system. To load and cock the barrel you simply push the barrel down (Break the barrel) all the way until you feel it cock. Load a .22 caliber pellet into the rear of the barrel (Breech) and make sure it's snug flush with the barrel. Load it with the skirt facing out and the dome in the barrel. Then bring the barrel back up into position and let it snap into place. AIM FIRE!
Well, it depends on what you mean. The caliber is "determined" at time of production based on whatever caliber the manufacturer wants it to be. The caliber can be determined later by looking on the barrel. The caliber will almost always be stamped somewhere on the barrel.
Unknown.
Usually caliber and/or serial numbers.
That would depend on the caliber, and type of bullet, the rifle uses.

Yes it is.
