My 92 PA uses R-12. That is also stated in the owners manual. Perhaps the condenser has been replaced and that means it can be used with either type??
Would have been built for R12, can be converted to R134a.

There were some R134a units in 1992, but they were not the norm. Most likely, you have an R12 unit, which requires retrofitting in order to be compatible with R134a.
It was built with R12, but will need to be retrofitted for R134a.

Yes, essentially all AC systems use Freon. After 1992, U.S. law required manufacturers to switch to an environmentally friendlier Freon, R134a.
