Carl Zeiss Jena blc Rm-F 12X60 für Em 4m R40 (View 3)
Interpupillary distance (IPD) is adjusted by moving a lever underneath the left eyepiece assembly which eccentrically turns the assembly to the required IPD. Note the two eccentric plates surrounding the left eyepiece. Also note: 1. the large slot above and between the eyepieces - turning the center knob projects a screw through this slot which presses against the faceshield raising or lowering it to adjust eyerelief. and 2. that below the right eyepiece there are two circular covers - one behind and one to the right of it - which when rotated give access to a Robertson (square) screw. These screws are for centering the reticle
Note: If you have a vintage binocular you either wish to sell or would just like some information about, I can be contacted at flagorio@shaw.ca .
