They really had the right idea back then, about how to efficiently refrigerate foods. And building them in two pieces means is much easier to move.
Heat rises, cool air falls, and back then they respected that science, instead of fighting reality, as they have been doing since they started sticking the evaporator coil UNDER the frig., back in the 1960s.
I'm not a fan of the look of having this large round structure on the top of the frig, but the genius was, not only was it air cooling the evaporator coils, the air flowed around the compressor as well. No energy wasting and noise creating fan necessary. If they could create a low profile version for modern frigs, that would be awesome.
This frig looks to be in pretty good shape. I hope the gaskets are good and all the racks are there.
