Sears 1936 Crosman 600 Air-Pistol in Box

Original 1959 Vintage Sears Model # 1936 Co2 .22 Pellet Pistol in Box with Manual and Infograph in Excellent Condition this is a Very-Rare Version of Crosman 600 that Sears sold for about a year. The Gun holds Air and Hits-Hard but the pointed-nose pellets that I tried in it seem to jam when feeding, I do not have any old style pellets to try so it might need just need a adjustment. The Box is in Good Condition with No Split Corners..
