Yep, the Crosley autos were made right here in Marion, IN. My Dad helped setup their production line after WWII, unfortunately they were selling a sub-compact car in the era of huge automobiles and cheap gas. After the war, metal shortages were a problem and by the early 50s they folded.
"Servel", is that the same as the RV and "off grid" refridgerators made by Dometic? I think they make a home model chest freezer that runs off a kerosene lamp burner, rated somewhere around 10F temp. The RV model we had seemed to cool off pretty well, nothing like commercial ice production but it would freeze a few trays in an hour or so.
