The freon, R-12 is damaging to our ozone and is not legal to
use today. This guy would be wise to get rid of this old machine
before the state air quality control board requires him to change
it over to R-134A.
Also the insulation used before 1970 had high levels of asbestos
and can be very toxic if inhaled!
That old brittle wiring on those old soda machines could short
circuit and start a fire at any time!
Oh yeah, and lead based paint ...............
