Mine was an Early 70's, made prior to 1974. I roiginally bought it in Smither's B.C., but sold it to a guy in Vancouver who mainly hutned small deer on Vancouver Island. It had the pop-up peep sight and was glassed in white, 2-ton epoxy. I gave the guy who bought it, the original .358 Norma Mag barrel with it. It had dies for each, along with brass.
