P125x or PX125

Just wondered what are the differences between a P125X and a PX125 ?
Cheers

p125x is early px that uses points and condensor, px125 is 12v electronic

Badges are no the same either…lol;D

I think not any!

Also differences in gearbox and size of primary drive shaft. On the very early ones you cant upgrade to efl type boxes because of this. Well you can but with some machining to cases.
