Nice site, full of information. I think he has some good sources. Helps a lot to rank the lenses by year - i.e. I didn't know exactly when my 1.5/50 was produced before... or that the 1.5/35 and some other were produced well into the 1970's..!
Otherwise, some more technical informations like these form the Stella brothers would be appreciated. Even Canon Museum hasn't diagrams for every lens.
cheers, Frank
