12 Volt generator with an original Pulley and fan!!

[Newc]

Hi all; this set up is on the cpe I just bought and it puzzled everyone. A 'Modern' Aluminum case generator with the original flathead Generator pulley and fan? Works great and looks right in a custom mount, uses the correct flathead single belt even. Can you figure it out from the photo?? Hint- it's German!! Look at the shaft protruding from the rear of the generator... for a FAN. Seems that someone got the Ford pulley to fit a VW generator... and to work right it takes a VW regulator. Arm, Field, and Batt are all there easy -peezy. What do you think of this fellows???
