About 1951, my folks bought a GE Refrigerating Machine (that's what the name tag on the back said). In '56, we and the fridge were transfered to the Nancy (France) Ordinance Depot where the GE ran off a convertor for three years. Then, we were transfered back to the states. It ran at that location until '78 when it was moved again. In '80, it was moved again. We sold it for $50 that year. It was still running just fine. Oh, it's bad to move a fridge, at least that what people were told in the old days. The old GE enduring two transAtlantic voyages, thousands of miles of freight trucking, getting yanked open probably 10,000 times (the door handle never broke), and probably 100,000 compressor cycles.
We replaced it with a Kenmore in '80. During the divorce proceedings, I gave that one away in September '04.
A good fridge can run a very long time. BUT, the new fridges are much more energy efficient.
Remember, it's always a good idea to buy quality when making a large purchase.
BTW, there used to be a brand called "Leonard." It was made by American Motors.
