Excellent comparison photo Rick, very interesting to see the difference. I don't think there are twice as many windings but there are certainly a lot more, presumably to produce the same torque at reduced current. I notice they're much heavier gauge on the 6V starter, presumably to operate at higher current. I'd be interested to hear the cranking speed with your 12V system, should be much the same the 6V system I imagine, which is good.
I had a quick look on a couple of hot rod sites and it turns out the 6V genny will definitely produce 12V satisfactorily, and some rodders only change the regulator. Others change the field coils in the genny as well, using 12V field coils out of later model cars. However I suspect that's more to protect them from higher voltage than anything else. Anyway it sounds like the armature is identical as I suspected, so the Lynx may simply use the standard 6V genny. Unless it has 12V stamped on it somewhere I think we can assume it's identical.
What all this means off course is there's no need to touch the genny when converting from 6V to 12V. Most people don't realize this and go to a lot of unnecessary trouble and expense.
