Wehrmacht 'Rundblickfernrohr Flak' (panoramic telescope). The telescope is marked with a three-digit makers code 'djg', indicating production by the company 'Joseph Veltjens KG', based in Berlin-Tempelhof. The telescope is marked with 'KF' (Kälte Fest) signifying that is can be used in minus temperature areas. The telescope is in good used condition, the optics are clear. It comes together with original often missing rubber eye-cup. Decorative item. A nice and honest piece of equipment!
