I checked the RCTech search function and could not find any information about my airbrush of choice.
It is the Harder & Steenbeck Colani airbrush.

I am not a professional airbrusher but I get professional results on Lexan and plastic every time even with problem (acrylic) colors like white and yellow. Cleaning is easier than with any airbrush guns I owned like Badger and Iwata since the cup can be removed and you get a direct access to the mixing chamber. Now painting with ten different colors in one session is not much of a bother.
Also the mixing chamber is very short, so only the cleaning brush and not the metal handle has to be pushed through. No danger of scratching the inside wall.
It looks funny but the grip and trigger feel comfortable right away and now my old airbrush feels strange and the trigger seems to be in the wrong place if you work for hours.
