122A vs. 126A vs. 129A L65 Drivers ??????

Ok. I figured out by doing a little research, my L65's are L65A's.
They have 122A 12" drivers in them.
The L65's marked "Jubal" have 126A's.
The L65B's have 129A's in them.
I have 3 questions:
1) Is any one of the models more "rare" than the others?
2) is there any other difference besides the woofers?
3) as far as sound quality, which drivers/models are prefered?

I've posted the schematics for all three models in another thread on this forum.

I see that you've already started to part your pair out on eBay.

The final revision is the most "refined".
Function follows form with the L65.

Thank you for the info Giskard.
Very helpful indeed!
