Raymic - Thanks for posting that. I have that buried somewhere. I tried searching that data online hoping to find a picture but to no avail.
Don Prince verified so detective work I was doing in regards to this annoying little topic for me. I am, by trade, a commercial HVAC mechanic as well as a history hound so I love old air conditioning/refrigeration equipment. That's why I have been trying to track down such specific info on such an innocuous little part of the boat. We still don't know what the evaporator cabinet looked like nor the complete compressor/condenser unit, but I have enough to make some semi-educated guesses.
Thanks to everyone who helped out. Now, on to the next insignificant detail that I can find to obsess on...
