A few days back there was a discussion of the venerable 2-stroke GMC diesel engine, and how it has managed to survive for so long despite the introduction of more modern and efficient engines.
Last weekend my wife and I visited the USS Silversides, a WWII submarine on display in Muskegon, MI. I found the engines interesting; they're 9-cylinder Fairbanks-Morse 38D8-1/8 diesels.

The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
