Bertin/Nervex Numbers on BB Shell. Help Decipher.
I am in the midst of restoring my Bertin and after sanding the bottom of the BB shell I noticed some numbers. I could faintly see these with paint on them but now you can easily see them. At first I thought it was the Nervex numbers but could it be Bertin info too? Anyone care to help decipher them?
Cheers,
GG

Is your BB shell trying to grow sideburns? What is that?

Well just for reference I was confused the first time I saw Nervex numbers and thought they where serial or model numbers. But ounce you learn to decipher them they can tell almost anything about a older frame high end frame.
This is from 64 Gitane with 531 tubing I sold cheap don't ask.

Bertin usually stamped a frame number on the non drive side dropout face.
As a code they are not useful.
