Ken, perhaps but,
could it be possible that Kelvinator built that machine back then?
Most of Borg Warners operations were still in Muncie Indiana back then.
I know the area well where the Kelvinator plant was. The front office tower still stands. The other plants in that vicinity were Detroit Diesel, a supermarket chain warehouse, and small machine tool and dye shops. Massey Ferguson was close, but in another postal code.
