About compur shutter

[Songyun]

how many different generations are there?
I read Kerry's website about copal shutter on Fuji lens, there are sort of 3 generations of copal shutters.
Anyone knows about how many generations of compur shutters (let's say post wwII)?
It seems that the latest is the all black shutter with B but without T. Does anyone have a time line for the different generation of compur shutters?

Songyun, P-H Pont presents one in his book Les Chiffres Cles. There's too much to type, it looks a little incomplete, and I'm not sure it will address your question.

You can buy a copy from FNAC. My copy is the 3d edition, when I bought it from Atlantida FNAC was still selling the 2nd, so make sure you get the latest. If the 4th edition is out, please tell us.

Thanks, I will check it out.

Dan, is that in French?

Of course. But there isn't much text and the dates and numbers usually speak for themselves.
