If that's all they are going for then that's a great bargain, they were probably the first big step in modern target air pistols from the FWB 65, with both a superb dropped wrist hold, and balance, with a superb trigger when set up correctly.

I had one of the first into the UK back in the day, and loved it, but we were restricted on their use then as they were initially on Fire Arms Certificate . I still have CP2 which is very similar.

You can get the cylinders resealed, and Walther also still have new cylinders for them.

Have fun
