iii) “beh” Marked with Rubber Armour, Serial # Range at least 440763 - 474439.

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.

Although often called “U-boat binoculars”, these were also much used on surface vessels.

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.

The market value of WW II German hand-held military jmk jk 109 видеоглазок binoculars is very high compared to those of other countries and 203c видеоглазок excepting китай the very finest купить видеоглазок записью с ones (most made by Zeiss and of 7X or greater magnification) does китайские видеоглазки not always reflect optical quality or rarity. The interior of the objective lenses, prism faces and outside of field lens are reportedly cryolite (sodium aluminum fluoride) anti-reflective coated which transmits light better than the usual magnesium fluoride but is more fragile. The exterior of objective lenses shows no traces of coating.

Note that extreme care must be taken when cleaning these old anti-reflective coatings.

Not only do they easily scratch and rub off but cryolite is soluble in warm water.

I cleaned gently with isopropanol followed by methanol with no problems.

====================== The optical performance of this binocular is quite good: it is better than the Ross Binoprisms and Barr & Stroud CF 41 especially in sharpness toward edge of field; noticeably brighter and sharper than the excellent Barr & Stroud CF 25; and somewhat kpc 190vi 170 видеоглазок brighter than even the coated B&L Mk 28 203c видеоглазок китай and REL’s. My only objection is that its rubber eyecups get in the way during viewing.

If this binocular was not collectable and I was using it every day, I would cut them видеоглазок беспроводной купить в украине off which I think видеоглазок kpc 600твл the Germans sometimes did. Ones made a little later in the war видеоглазок дверной купить had hold-back tabs molded in the rubber to solve this problem.

NAVY BU.SHIPS MARK 28 MOD 0 7X50 Field of View: 7 deg 10 min = 124.5 m 1,000 m; APFOV 50.12 deg Weight: 1353 gr Exit Pupil: 7.14 mm Serial # Year of 203c видеоглазок китай Manufacture: 170434 = 1943 1944 Значительно более эргономичная, близкая к современным, модель.

Optically this is one of the best circa antibug look дверной видеоглазок WWII 7X military binoculars in collection being, I think, just a little activision видеоглазок схема bit sharper to edge than the best of the 7X50 REL's.

The beh Leitz 7X50 is a little brighter, however, and also has good edge of field sharpness.

Mark 28 was manufactured from 1944 – 1945, but continued to see service with U.S forces 203c видеоглазок китай well into the1980’s.

Although he states that they were not originally coated, this being done kpc 500b он 170у видеоглазок 203c видеоглазок китай only upon reconditioning, I believe this applies only to the earliest ones produced and that intellicorder видеоглазок дверной цветной those made in 1945, at least, were coated upon manufacture.

The above example does have coated optics which was probably done during a later reconditioning.
