I remember seeing those freon guns in the back pages of all the gun magazines. Never gave them much thought but icing up did cross my mind. R12, how common it was to use it for the heat/cold treatment on rusty fasteners and seized components on cars. Then again we blew brake dust away with an air hose and kept on working. Freon, asbestos, solvent fumes....how did we live this long?
Air guns and magazine ads: I still have one of those Chinese side cocking air rifles. They were $19.95 or $29.95 or something at the time. Turned out to be very accurate and almost twice the advertised velocity. I chrono'd it at an average of 920 fps. In spite of the heavy, spongy trigger I still have it.
