Restoration of Japanese pneumatic wrench | Restore pneumatic guns Welcome to my next restoration project. While walking around the old tool market, I visited one of the stores and found the tool I needed. a very old Japanese pneumatic wrench, aluminum cover and translucent blue coating. The engine part is stuck and cannot be started. On the shell has the “NPK“ braille. It is a pneumatic guns brand of Japan. I bought it for $ 5. I brought it back to remove each part of the machine, clean and clean the rust.
