I have one bought new back in late 1974 or early 75 from the old Air RIfle Headquartes in W. Va. It has been through two piston seal replacments/rebuilds in these years, the most recent last winter. My son and grandson were coming over and the grandson was wanting to shoot so I got it out after too many years of inactivity. It would only move the pellet a couple of inches and seal material was coming out of the cylinder vent hole. I sent it off to David Slade at Airgunwerks.com and it came back better than it ever has been. We were out shooting it this afternoon and my arm got sore from all the cocking. I had one of the Beeman Blue Ribbon scopes on it probably close to 40 years and went back a few weeks ago and put the Williams receiver sight back on that I had for a short time before the scope. Even at 75 years old I seem to have more fun with peep sights than with scopes, plus this rifle just handles better with iron sights.
