I got mine for Christmas in the 70’s. We would shoot wooden match sicks at 50 ft. Dead on accuracy. In the 90’s, sent it to Sheridan for a refurbish. Still, dead on. Today, I ocasionally drop a bit of oil in it to keep the piston lubed. I think the original piston may have been leather.
Regardless.. I don’t mind pumping, and it’s a bit loud but, I hit where I aime. My classic will be handed down.
