I don't think it;s anyone here but whoever writes theses pages they don't do much research.
Claiming that CZJ released the f4.5 Tessars in 1917 ? where did they get that from. I was checking SN's today after buying a very early 135mm f4.5 CZJ Tessar in a sunken mount which appears to have been made 1909/1910 and checking my BJP Almanac for that year they are widely advertised including second-hand, and also made under licence.
Elsewhere statements that the first Tessar patent was for an un-produced f5.5 Tessar, yet I own one a mint CZJ f5.5 165mm Tessar bought from a member here and Kodak advertised them on a couple of cameras, they are not very common though :D
