So it seems that Brian has stumbled onto the mystery cooler. Did you buy it Brian? That would look great all cleaned up with a fresh coat of paint. Although, with my wife's family ties to Coca Cola I could never get away with that one in my house. Canada Dry, RC and DP but not Pepsi!
I have to agree with the posts so far that it does not really look like a Pelco or a GE. I was thinking maybe Kelvinator but it really does not look like one of those either. The size and shape of the cap catcher is certainly unique and should eventually lead to the ID. Could it be an Atlas? They used the bottle cap embossing on their coolers.
