Clean it good first.
Likely it is a Pietta, and new cylinders and parts are available for it.
Does is have an FAP in a diamond somewhere on it?
Is there a square with a couple of letters in it near the serial numbers or on the side of the frame or barrel? That will give us the year it was made (Italian date of manufacture).
Either place lube on top of the balls or use wads under the balls to keep the gun from chain firing and keep the fouling softer.
Usually, these guns shoot to point of aim (mine does) at 25 yards.
Just be certain to clean out the inside of the action- it doesn't take much rusting for the trigger/bolt (cylinder stop) spring to rust completely through!
Extra cylinders for this revolver are very expensive and preclude obtaining an extra one unless you really love it. Not exactly the most common replica, but a good one.
I got mine under the Traditions label, and it's a smooth shooter- bottom right corner:
