trying to get more info on a rifle I was given by my bro-in-law, one of several. It is an Ithaca model 14-49R, .22 long rifle, 19" bbl, lever action. SN starts in the 5001xxxxx area. Anyone have any experience with them? Just a hurtin' to try it out, Already had it apart and it all checks out, in great condition......Love my family
