Caliber 44 RF. Replacement rear sight. Original front sight. Buttstock and forearm have been replaced some time ago. A decent job with the carbine style buttplate. Overall brass show a fair amount of use with some polishing on it at one time, starting to turn darker. Some rounding to the corners. It appears that the lever has been repaired at one time. Replacement barrel band. A fairly priced 66 carbine.
