TELEFORTEM 12X with ORIGINAL STRAPS/N 362069A very rare example of the 1913 Carl Zeiss side focus 12×30 Telefortem. It is rare because both eyepieces were focused in unison by twisting the right eyepiece, the left eyepiece having the independent dioptre adjustment. This system worked because the binoculars depth of field is very shallow and so the amount of movement to focus is very small. However, only 39 examples were made before Zeiss switched production to the 12×30 Telefortem with centre-wheel focusing.LESS THAN 50 MANUFACTUREDHOW MANY SURVIVED TILL THIS DAY…?CARL ZEISS JENAGOOD CONDITIONslight fungus, no scratches just cleaning marks, no haze, specks of dust. This binoculars need servicing. Both eyepieces focus in unison by twisting the right eyepiece. It doesn’t work. Helicoid is grinded. DO NOT HESITATE TO ASK QUESTIONS!
