K Frame 22LR cylinder with yoke. Will fit Model 17 etc, and should fit the Model 48 Mag if you want an aux 22LR cylinder. Length is 1.62", 6 shot. Excellent for reaming out for one of the 22 cal wildcats. Very little finish remaining, no rust or pits. $100 shipped to lower 48. First unconditional I'll Take It followed by a PM.
Thanks
David
