Walther LP53

The LP53 (LP stands for luft pistole - German for air pistol) was an early (1953-1983) attempt at making a .177 target pistol.

It copied the lines of Walther's famous .22 LR Olympia target pistol, and it used a spring piston to compress the air.

When you look at the pistol, you wonder where the spring and piston could be, but they are tucked away inside the pistol grip.
