The Savage 170 pump rifle was made from 1970 through 1981.  The rifle version (22" barrel) came in 30-30 or 35 Remington.  The carbine version (170C - 18.5" barrel) only came in 30-30.  There was a plain version and one with an engraved receiver.  It has been reported that the rifle was based on Savage's 20 gauge shotgun frame and some parts are interchangable.
