Gene - A couple thoughts:

1 - If generators are otherwise identical, the resistance of the field windings on a 12 volt generator should be about double that of a 6 volt. (Note: As field winding resistances are quite low in both cases you'll need an ohmmeter capable of reading to 0.1 ohm - ie. a digital voltmeter - to accurately measure winding resistance.)

2 - Generators ARE rotation sensitive. Brushes are positioned - and often also angled - for operation in only one direction (usually clockwise when looking at the drive pulley)

----

Incidentally converting to 12 volts to deal with a slow cranking condition is only a temporary, "bandaid" fix. Your Allis should spin over just fine on 6 volts if everything is up to snuff. Requirements are good battery, suitably heavy battery cables (not the cheap "12 volt" cables like are sold in auto parts stores...), a good starter switch and of course a healthy starter.
