Sry DaveG. I know you have incredible collection of airbrushes, I didn't think you will go digging for Paschee. It was more a question if you know maybe.Man, you had me digging all the way to the back of the cabinet... I did not check the threads, but because the nozzles are so very different, the inner construction of the cap is so different, that the Paasche head will not fit over the Iwata pieces.
