This is my grandparent's air conditioner, I took it out for cleaning. I forgot to take a picture of it back installed in the wall, but I took pictures of it while I had it apart letting the coil cleaner soak. The unit is about 30 years old, its a Carrier, and it runs perfect. Its very powerful. This thing has so many hours on it and it just keeps on going. It has a Toshiba compressor in it (not sure what type of compressor it is though) and a General Electric fan motor.
