Have two Tingle pistols, both 3-digit serial #'s. One my father bought in the 60's, the other I acquired maybe 20 years ago. At the time Dad bought the first one we were at the Bagnal Dam gunshow at the Lake of the Ozarks. I remember the display not only had the single-shot pistols but an array of various barrels, a shoulder stock, at least one if not two rifles as well. Recently I acquired a rifle barrel which has taken a long time to find. Anyway, does anyone have at least a photo of the shoulder stock? I realize finding one of those is probably not going to happen. Simply would like to see what they look like. Thanks!
