The type iii) is the most common variant but in good condition with rubber armour intact may have same or greater value than the other types. Although often called “U-boat binoculars”, these were also much used on surface vessels. This type has coated optics, desiccant cartridge housings and is rubber armoured (often missing in part or whole and/or in dilapidated condition) with different style ocular housings than previous models. iii) “beh” Marked with Rubber Armour, Serial # Range at least 440763 – 474439. Seeger shows such a binocular (serial # 431687) on page 291 which is identical to this collection’s example pictured above. Later examples beginning with at least serial # 431583 do not have these two markings but still have coated optics and additionally have housings for silica gel desiccant cartridges on the prism plates with each prism plate secured to the chassis by a large ring instead of screws. Earlier examples of this type are marked “T” indicating coated optics with a Kriegsmarine eagle.

ii) “beh” Marked without Rubber Armour, Serial # Range at least 328770 -436830. This type also has a Kriegsmarine eagle marking and usually does not have coated optics. Leitz Wetzlar” Marked-Serial # Range at least 238203 – 310223. Notes: World War II Leitz Porro II 7X50 binoculars (called 'tuna cans' by the Germans) are serial numbered at least 238203 – 474439 (however, this is not sequential because other model Leitz binoculars have been seen also manufactured and serial numbered within this range) and, as suggested by Rohan, can generally be divided into three types.
