Paasche ABL Turbo (Left Handed). I've not seen a Paasche with a metal handle, but I do know they were offered. This was for sale in Canada, but I don't know if it's still available. As a lefty, I could use this brush. It's beautiful!
1930s Paasche Model MLS. This airbrush was the pre-cursor to the Paasche VL series airbrush. The patent year on the body is 1928. This airbrush is unusual in that it has an adjustable collar that pushes the trigger back — more or less making it double as a single-action airbrush.
