12V motors readily available to match the physical specs of the 6V one [size, speed, rotation direction, shaft],
When I rebuilt my heater a while back I had a heck of a time finding a 12v motor that matched the 6v in apperance.
I found a tip on
DEVE'S web site .
He placed a new 12v motor in his
6v housing. I did the same thing and was very satisfied with the results.
This will not answer the original question to this thread but may be an option for others
