Lynkeioskop Serie E, f:7.7, in 9, 12, 15, 18, 21, 24, 27, 30cm (Universal-Aplanat)
Weitwinkel-Lynkeioskop Serie F, f:15, in 6, 9, 12, 15, 18, 21, 24cm (Wide angle aplanat)
Do you know if Goerz ever made shorter focal lenght of LYNKEIOSKOP?

I have seen Goerz Extra Rapid-LYNKEIOSKOP Serie C, No.1 (I could not check the FL). No.1 suggests rather 6" than 9".
