Cool CT , hope you can locate one and pass the information on to me if you would, my first paint gun When I was 22 years old was a JGA 502 in 1982 , in my opinion the best custom paint gun ever!! It would spray anything but it shined when spraying lacquer Pearls and candys !! You could spray from a pencil point to a 10 inch fan perfectly, I still have about 10 of them in the shop somewhere In a box although I don’t use em very often anymore, but I do have a JGA-502 tattooed on the back side of my forearm!! Thanks CT , Gary .
