Let’s look at an old air rifle that left the world stage several decades ago. The Bayerische Sportwaffen Fabrik (Bavarian Sporting Weapons Manufacturer) or BSF, as it was known, operated for several decades after World War II. They were based in Erlangen, Germany, and the guns they made were approximately equivalent to Dianas, though in some aspects they were the better brand. It was BSF that first broke the 800 f.p.s. barrier with their model 55 breakbarrel. They remained at the forefront of the airgun horsepower races of the late 1970s and early ’80s until the Beeman R1 buried the field. Then, like everyone except Diana, they gave up.
