No matter how you got it it's sweet, and you're showing solid interest in doing her right. Much respect sent. Does it have the old RV-2 compressor? A big heavy V 2 cylinder design? Not very effecient, but man they blow cold. I have several. I can get part numbers if you need them. Several companies in the US will rebuild them for you, and you can convert them from R-12 to R-134. PM me if I can help you, young man.
