thanks all
Thanks all for your comments. I am so excited to find something so rare. Yea it is super quiet too, one fan speed and not a strong one like "gyrafoam" said. You can barely hear the compressor it is so quiet, but those coils get cold quick. The vent and exhaust doors are HUGE too !! not like the little tiny flaps today. It is rated as a "1 ton" so about 12,000 btu's and of course it weighs I think around 150lbs. I can't believe they use to put big units like this in the window.
