There are three Tippman Browning miniatures for sale at the Rock Island, September 6th auction. A Model 17, Model 19 and a 50 Cal. HB. Does anyone have any insight into these 1/2 scale models or advice about what to look for if one is considering bidding? Being new to the world of full auto (patiently waiting for my Form 4 to be approved) and from the Fort Wayne area, the Tippmans fascinate me. Any feedback would be appreciated.
