[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I've just bought a screw-mount 135mm f4 Hektor, and notice that there are some markings scratched into the rear of the optical head: 1R XX H 134 5 I"m guessing that "134.5" is an indication that the exact focal length is 134.5mm (would Leitz still be making such improvised markings in 1957?) but am mystified by the remainder, which seem to have been done by the same individual. (I wondered if the 1R was IR, but the first character looks like the common European style for a hand-written 1) Regards, Doug Richardson
