Crosman model 1400 Pumpmaster .22cal. (1976), Sheridan CBW Blue Streak .20cal/5mm (1972), Benjamin model 317 .177cal/4.5mm (1940-56)
Since I bought my Benjamin Model 317 from Mr Marvin "the AirGun Guy" last year, I have thoroughly cleaned and oiled the exterior metal & stock, as well as that, I cleaned and lubed the pump arm,pump cup and seals that I could without fully disassembling the air rifle.
