This is a handsome fridge, but I can't make out the emblem.  It also appears to have brightwork at the bottom that may read "Automatic Defrost."  How would that work?  Like the Westinghouse system?

It's in beautiful shape for the price.  Probably had an easy life in a Lake Tahoe area cabin.

Seriously though, would a MW fridge from this period be a Westinghouse, a Frigidaire, or an old Norge of the SNL skit genre?

Hmmm.... Norge would be my first guess. 

When you look at a beautiful old tank like this it makes me think of how these models were most probably the first electric refrigerators that their owners ever had, and what a joy they must have been to them. 

I reflect on the hours of work, that my Father described to me in great detail, required by his parents' ice box in their NYC apartment in the Thirties and Forties (and they were lucky to have one) just to keep a fraction of what that MW could keep cold with some cheap electricity and a relatively small amount of elbow grease to defrost the ice chest once a month.

Sometimes it's good to count your blessings.
