Additions to Vintage Binocular Collection
The following have been added to my collection since the last posting on ugust 23, 2013:
. It is interesting to see, Ben, that your 20×50 has a field of view of 7.8°.
Not bad really.
LPT, post 182,
Very nice list of vintage binoculars. I have a question: in your list about the Leica-Kern Arau you write that this binocular was made by or inspired by Leica. However, I have a Kern-Arau 8x30 from 1984 (Hans Weigum was so friendly to supply me one), which looks exactly the same as your 1991 instrument. Morover I have a Leica 8x30, identical to this Kern-Arau 8x30 (labelled Leica and not Kern, with a low production number) and supplied with laser protection filters.
Moreover there is a Kern-Arau 8x30 Pizar which is fully identical with the military Kern-Arau 8x30 except for the focussing mechanism, which is not separate eyepiece focussing but central focussing. I found it in a Swiss shop around 1985.
So, what made you conclude that the Kern Arau 8x30 from 1991 is a construction invented by Leica, since the 1984 Kern model was already produced by Kern in 1984, when Leica was nowhere to be seen as far as I know, but Hans Weigum may know that much better.

From what I've seen the Huet military binoculars are much better constructed than their civilian models particularly the Huet post-war civilian ones.Hello LPT,
My one Huet, 8x30 M.G. Mod. 1956, has the feel of solid construction, which I gather is typical of Huet's military optics. I like what looks like a reflex finder on the Nikko.
Happy collecting,
Arthur :hi:
Thank you Hans and Gijs for the information.LPT,
I received the following information about Kern and Kern binoculars from Hans Weigum:
-1-The company started its production in 1819 in Arau
-2- Production of binoculars started in 1925 and production lasted for 65 years until 1990
-3- Binocular and monocular models produced: Alpin Lux 6x30, Alpin Stereo 8x30, Alpin Super 12x50, Alpinmono 6x24, Armee modells 6x24, 6x30 and 8x30. The last one was also procuced with laser protection filter and rubber armoring, Focalpin-10 10x60, Focalpin-6 6x40, Focalpin-7 7x50 .
The company was sold on Mai 13, 1988 to the Wild-Leitz group and the company was renamed to Leica Arau in 1990. In 1991 the production facility of Kern & Co AG in Arau was closed.
So I think, that Leica did not have any influence on the design of the 1984 Kern 8x30 army binocular, which I have shown in my photograph. The Kern 8x30 military from 1984 without laser filters is rather scarce nowadays, since many of them were supplied later with laser filters. From the civilian Kern Pizar 8x30 with central focus and rubber armoring only a few were made rather as a by-product of the army contract.
Thanks to Hans Weigum for ths information.

I would appreciate any comments, further information or corrections the members of this forum could provide about these binoculars and my descriptions of them.
Once again, thanks to members of this and other forums who have provided new information about the binoculars in the collection.

Dear LPT
As Gijs asked me for informations on Kern binoculars, I would like to add the following warning: The design of the Kern/Leica is unique in so far, that for reasons of more economical production and maintenance, each completely assembled half gets its mating surface at the hinge machined in a special device aligned to its optical axis such, that later randomly taken halves may be mated and will be collimated at once. So be careful taking apart this binocular, when you have no access to such an alignment machining device. World wide there might be only two of them, one only left operational.
Hans,
I noticed that the Kern's objectives do not have eccentric rings and thought the binocular was permanently collimated at the time the prism assembly was glued in place. However, according to your mail collimation is achieved at the hinge. Two questions: - 1) Is this collimation permanent or can it be adjusted by movement of something like eccentric bushings inside the hinge? 2) How strong is the hinge mechanism and do these binoculars easily loose collimation? My impression based on descriptions of the ones I have seen for sale is that it is strong and they seldom loose collimation . The only other binocular I have seen like this one which collimates at the hinge is the Avimo 7X42, but during the Falkland War it was reported they had problems maintaining collimation. I think this is not so much because the eccentric bushings in the hinges shifted but because under rough usage the rather thin hinge lugs tended to get bent.
. Why aren't all binoculars made like this so that the two halves will be in perfect collimation? With the mechanical and optical axes all parallel.
I was told that this could not be successfully done but obviously it can be. Maybe it is just too expensive and needs special technicians.
