This is a very nice original SA Sports badge with much of it's original bronze finish remaining. Some wear is present, and visible in photos. On the reverse is inscribed "Eigentum der Obersten SA-Fuhrung" along with the maker mark of W. Redo, Saarlautern. The catch of this badge is slightly bent, it appears to have honest wear from use.
The SA Sports Badge was instituted on 28 November 1933 by then SA chief Ernst Röhm. It was originally only issued in bronze through the year 1935. On 15 February 1935, Hitler decreed that the badge be officially recognized. It was thereafter issued in three grades (bronze, silver, and gold). No longer was the physical fitness badge to be awarded only to SA members, but to youth of all German military and paramilitary organizations.
