Out of my curiosity, I started to study the TTH cooke portrait soft focus Series generation transitions.
The original thread reply is here.

I am hoping to sort things about what Barbara, the former historian of TTH Cooke (I heard from Ivan that she retired several years ago and resides in California), said about the “six incarnations” of Series II portrait soft focus lenes.
The whole archive was donated to Margaret Herrick Library, according to Ivan.

Here I decided to collect the facts of lenses, sample pictures and actual samples in hands of mine and others, rather than supposing how many generations existed. In the end, I could safely say how many there are….
One of my questions is now solved with two samples in hands about the title, if there are any soft focus generation differences between Series II Portrait knuckler and IIB knuckler.
Conclusion: no difference. This implies IIB and II knuckler soft focus lenses were not made at the same time.
PS: the aperture blades count the same for both, 12.
