I've owned Ruger Mark I and 2 autos, but the other day I found something I couldn't pass up -- a Ruger Mark I air pistol, made in China under license to SR, Inc. It's not listed in Wilson's book Ruger and His Guns so I'm asking for details here (and in the revolver section). It's a clumsy looking .177 caliber, spring-piston job with plastic grip section and a cylindrical steel receiver grooved for scope mount. this one had a Bushnell Banner 2.5 rifle scope mounted way back, making it useful only for two-handed bench shooting. The trigger pull is terrible. The seller said it originally sold with some kind of device to go around the barrel for pumping -- the big front sight makes cocking difficult without using a pad or wearing a glove. Can anyone tell me when it was made and what the cocking device looks like? Pix would be nice, but I'm hopeless on that score.
