These are vintage, full cans of X-ACTO Powerpak airbrush propellant, part No. 8090, (from their 1980 catalog).”15 ounces on non-flammable propellant that easily attaches to FINISHING TOUCH and MAGIC TOUCH air brushes for a complete air brush system”These probably have universal air propellant threads, (buyer to verify on their own before purchasing), so should fit most any air brush. I tried it on a vintage Badger air brush and it was fine.You are purchasing 6 cans.May have a couple vintage Paasche, (1940’s and 50’s), air brushes coming up for sale, NOS in their original boxes soon!
