Nevertheless they are good horns!
They are to be found under many aliases since they were pretty much the equivalent of the nowadays Chinese or Taiwanese saxophones in the '70 and '80 market. B&S are also known as Weltklang, their best model being the " Solist" model) but lots of people favour the Blue Shield (or label) as it was supposed to be their best production. I have played a number of them and , in fact, the later " West-German" B&S were still based on these horns but the better series (Guardala, Medusa, 2001, Codera) had much improved keywork on a bodytube that stayed the same (but in general had a better execution and more attention for details), the B&S blue shield were essentially the same as the B&S series 1000.
