about thirty five years ago, my sister gave me a paasche H series air brush. since I didn't know that the heck it was, I put it away. several years ago I started to use it. my original brush came with a cup for painting. since then, I have bought a HS type tip and paint jar.I use the jar to mix paint, then screw it on and paint.
One observation, keep your empty paint jars, buy several siphon tubes. drill main holes, and vent holes. then you can mix and keep unused paint in the sealed bottles, and simply screw on the color of choice and spray it. the clean up would be only the siphon and cap assy, and the spray tip/needle assy.
