Unique numbers on generator pulley

[Mister.64]

Long time reader and first time posting- looking for some information. Restoring a ‘64, numbers matching car. Looking closely at the generator pulley when I got the car, I noticed painted numbers. All odd, 1-35 some are very visible. Can anyone share what these are for? I’ve never come across this before in pictures and not seen these on another. They look original.
( i hope there is enough resolution ) I don’t plan to paint the pulley or clean it...don’t want to risk removing them!

It's a code for ancient mysteries relating to the children of Jesus.

My numbers matching '64 has the numbers on the pulley also.

Are they 4, 8, 15, 16, 23, 42?

Careful guys, if you run the engine backward, you’ll hear a satanic message.

Moved from the Ghia zone.

Here is a photo of a 40hp generator rear pulley half. It's from a 1962 Ghia engine which from all appearances it seems to be a relatively unmolested July 1962 motor.

This reminds me of the numbers to be found on Judson Supercharger rotors. They were balanced on a Gishault Balancing Table. The end of the rotor had numbers printed on it and the numbers illuminated by the strobe light on the balancer indicated the area where metal had to be removed to balance the unit.

You'll only find these numbers on a NOS rotor as gas washed off the numbers very quickly.

However I can't imagine a generator pulley would need to be balanced.

Wonder if the factory unit of pulley and armature of the gen installed in each VW were balanced together??

OK, this is totally speculation and faded memories but I seem to recall reading that VW balanced the generator/fan/pulley assembly by adding weight to the outside pulley half, like the weight shown in my photo above. I don't see how that much weight on such a small diameter pulley would be an effective balancing mechanism but maybe those fans were really close to being balanced and it only took a little but of weight to make them run smoothly. I'm not sure how the numbers would work into that but maybe John Moxon's Judson rotor balancing theory would fit into this.

Also found these numbers on the generator pulles.
I read 27 29 31 33 35

Still a question for what these are standing for
