Is it an old or a new one? The new ones have safety catches.
They are the smallest HW springer rifle, a tiny one for juniors to practise with. They have been around for decades, at least since the 1960s.
Simple, heavy trigger for 'junior' safety, easy cocking and give about 6 fpe. The trigger is not on a par with the Rekord or Perfekt triggers that give Weihrauch its winning character so that is disappointing, but in comparison to say a BSA Cadet it is acceptable.
For an adult they make interesting little plinkers.
Not nearly as nice to shoot as the HW30, but they are so light you can shoot them one-handed like a pistol.
