It should be R12 but could be R134a, easy way to tell is to look at the A/C service ports, if they have treads on the outside, [like a bicycle tire air valve] and both are the same size, [or close] it is R12.
If the service ports are "quick release", [kind of like air tool couplings] with one much bigger then the other, then it is a R134a system or a R12 system that has been retrofitted to R134A. 94
