Something I remembered to mention 2 seconds after posting is that 12V on a 6V field that wasn't already burned wouldn't particularly stress it.
The strength of the magnetic field develped would also be doubled with the 12V instead of 6V. This would also increase the generator output voltage. This would reduce the duty cycle time and heating concerns.
The soft iron cores are pretty large and the field windings modest. The excitation wasn't being driven into saturation.
So if the 6V generator was running at more than just the break even rpm to make 14.4V and the field wasn't enegergized 100%. The smoke shouldn't have got out of the windings.
The person doing the origional 6V to 12V conversion wasn't a pro. There was a 6V system that wasn't working and they threw a 12V battery and regulator into the mix and have come up with the conclusion that the conversion ruined the generator. Sorry, it was already toast before the tinkering started.
Install a new field, a regulator that doesn't weld closed and enough rpm the field is energized only 30-70% of the time and it will be fine.

Harvestin Hay: The Early Years (Part 2) - by Pat Browning. The summer of 1950 was the start of a new era in farming for our family. I was thirteen, and Kathy (my oldest sister) was seven. At this age, I believed tractor farming was the only way, hot stuff -- and given a chance I probably would have used the tractor, Dad's first, a 1936 Model "A" John Deere, to go bring in the cows! And I think Dad was ready for some automation too. And so it was that we acquired a good, used J. I. Case, wire tie hay baler. In addition to a person to drive th
