Like most things technology has a lot of my stuff old school. That pump up made in Racine, WI. Silver Streak looks good on the outside, but the valves don't hold air any longer. It was great rifle in my youth, but I've since discovered Aguila Super Colibri and CCI Quiet Segmented HP .22 LR ammunition that kills as well or better than that .20 caliber Sheridan with the equivalent noise level.
