I would like to ask any one who can contribute to post photos of voltage regulators (up to about 1950) - if possible with internal parts exposed. Thank you very much.

I found some interesting pictures and drawings on the net and put them in the gallery. There are two different versions, one with the current winding made of round wire (for 90 W dynamo, 2 1/2 turns coil) and other made of flat wire with a larger cross area (for 130 W dynamo, 1 1/2 turn coil).
The pictures give some idea how the battery charging circuits are designed and how the regulators work.

Why does it matter what the inside looks like?

Is the color really all that matters???
