    RN binoculars

    I can think of three military roof prism binoculars with graticules - the Canadian ELCAN 7X50, the U.S. Army M24 7x28 and the Zeiss Jena EDF 7x40, but there must be more. But all of those mentioned, however, are IF’s with conventional eyepiece adjustment focusing. I’m not aware of any Steiner...

    Vintage Binoculars Help

    The binocular in question is a civilian model and was likely made circa 1919 - earlier 1920’s. Hensoldt did make some Porro I binoculars with widely spaced objectives between about 1900-1905 in violation of the Zeiss patent which would not expire until 1908 (see Seeger blue book pages 378-378)...

    Did the US Navy Use Japanese Binoculars Prior to WWII?

    I‘ll bet the binocular was a center focus one too which was almost never the case for WW 2 period binoculars (unless it was a private purchase or one donated by civilians).

    Did the US Navy Use Japanese Binoculars Prior to WWII?

    “Looking on IMDB someone said that the US used Japanese binoculars prior to the bombing Pearl Harbor. Is this true?” No, this is absolute nonsense. Prior to Pearl Harbor U.S. forces used mostly U.S. made Bausch & Lomb handheld binoculars together with a small number of naval Zeiss binoculars...

    CZ 8x30

    Not all of the Oberkochen Zeiss were marked, “Made in West Germany”. I have some examples which are marked, “Made in Germany”. Why, I don’t know, but it may have been a political statement.

    CZ 8x30

    They’re definitely authentic but West German Oberkochen Zeiss, not Zeiss Jena. The company split in 1945. Today’s Zeiss is the West German one. The East German Zeiss Jena ceased operations circa 1990.

    Carl Zeiss Deltrintem 8x30 - are these legit?

    Yes, they were made in 1920, an early example. The first ones were made in 1919.

    Binocular help

    Zeiss factory records which are usually accurate show that 34068 was a “gasmask” model manufactured 1942-1943 much like this one in my collection: https://www.flickr.com/photos/binocwpg/8555893220/in/photolist-nv5exo-e34bYm-H3PX8H-GekMas

    Very nice. First one I’ve seen.

    Avimo or Rollei 7x42?

    Hmmm, I stand corrected. This could be a Rollei as well as Avimo, alright.

    Avimo or Rollei 7x42?

    It’s an Avimo missing the serial number plate which is fairly common.

    Lumenised?

    Yes, the objectives are 50 mm and the magnification and field of view specifications seem to be about right.

    Lumenised?

    The Lumenised marking is a sales gimmick and nothing else. It does not indicate any sort of actual innovative coatings or optical glass etc. this particular binocular has although it may have origins in the markings of a much higher quality instrument. Quite a few low-budget Japanese binoculars...

    Serial numbers and date of manufacture

    See post #’s 9 and 10: https://www.birdforum.net/showthread.php?t=375572 I maintain a small pre -1963 Leitz binocular serial number database and can help with the earlier binos.

    Royal Navy current use binoculars?

    Those look a lot like the US Fujinon M22 but I checked mine and there are small differences. So I don’t think so. But what are they?

    Kanji translation request on 10x50 wide field

    The binocular’s 100% original WW 2 Japanese Navy. And it’s a rare one. The eyepieces are almost surely Erfles as on the Zeiss/blc German WW 2 Dienstglas 10x50. I would love to see a translation of the writing on the case.

    Kindly help date / identify this CZJ 4x bino

    "The 4X14 in Seeger's book that has identical engraving on the right side prism cover plate is SN 3836 and he dates as about 1906. As John indicated, the Zeiss Lens Logo on your left prism cover plate was introduced around 1906, the earlier binoculars had an elaborate script logo and script...

    Zeiss: Collection of cross-section and cutaway images

    All air to glass surfaces in the Amplivid area coated. The Allbinos article pretty accurately describes my impression of the binocular. Regarding its off-center edge of field view Allbinos notes a lot of distortion but adds, "What’s interesting, though, the distortion didn’t make itself felt."...

    One other thing, check to confirm that they are, in fact, 6x. If they are a reworked circa 1920's French military binocular, they could be 8x32, the French army preferring this configuration whereas the German, American and British armies preferred 6x30's or 6x24's.

    zeiss telex

    This is an unusual binocular. Referencing Seeger’s blue and green books it is clear that the ocular end prism plate screw arrangement on the “mystery” binocular differs from those on the Telex 6x21 (Version 1 Telex), DF 6x24 and Telex 6x24 (Version 2 Telex). I have attached illustrations...

    zeiss telex

    Gijs, I think I’ve seen Zeiss binoculars with 64 and 74 degree graduations on the IPD plate, and the zinc prism plates are characteristic of circa 1918-1920 manufacture. As well, the lack of the usual metal cap on the objective end hinge could be because of the exclusion of the military IPD...

    zeiss telex

    Dr. Hans Seeger’s two books, Zeiss Feldstecher Handferngläser von 1894-1919 (blue book) and Zeiss Handferngläser 1919-1946 (green book), are in my opinion the authoritative works on the subject. Both are meticulously researched and scholarly, richly colour illustrated and voluminous. However...
