lines are now hard to follow. My Kronos glasses are typical-excellent optics and basic but passable mechanics.
Lastly, I like to report a recent pilgrimage I made. While in Philadelphia for a medical meeting I visited I Miller on 35N Second. This is in the historic district, right across the street from the old Christ Church of Revolutionary War fame. An unassuming one store wide but very deep old building now filled with microscopes. They are the largest supplier of microscopes for educational purposes on the East Coast. In the past they wer the prime contractor to the US Gov't for binocular repair in the WW2 era. They still have a vast storehouse of parts and pristine leather cases. In the back they have cabinets of old binocs in various degrees of repair-German, US, Japanese, French. I found a number of interest. Perhaps the best was the NGF heavy duty 6x30 seen in Steve Rohans book and starred as very rare. A potential source of spare parts for the more creative of our group. I Miller no longer does any repairs of binocs. --Arnie
Subject: Recent design developments.
I have only just discovered what appears to be quite a novel eyepiece arrangement that has been incorporated into the 2002 Bushnell 20 -60 x 60 spotting scope.
It is a multi -position pivoting eyepiece which offers an infinite number of viewing angles ranging from straight through to 90 degrees .
I have not seen the item in the flesh but it certainly sounds like a most interesting development that could be of great benefit for many utilisations and one that I'm frankly quite surprised hasn't caught on with other manufacturers.
Perhaps there are inherent problems ?
I wondered if this system had ever been tried before ?
As a side issue , another good idea that I'm surprised hasn't been copied by other leading manufacturer's is the twin -power eyepiece system of the Leica Duovid , now also available as a somewhat bulky 10 and 15x 50 version.
Other unorthodox developments are to be found on the Leupold Tactical 12 -40 x 60 spotting scope . Unlike most modern scopes it uses erecting lenses instead of prisms to both erect and laterally correct the image , and uses mirrors to fold the light path , giving the scope a very compact " double decker " appearance .
As for relevence to this group -"after all today's developments are tomorrow's history" is about the best I can offer . Kenny J .
I'm not sure I've ever seen a spotting scope with a swiveling eyepiece. This site has a large image:

I have to make a comment on Mike Simonsens contribution. There have been some binoculars found labeled "Norinab". Hans Seeger once told me that these were put together from Zeiss parts remaining in Sweden after the first World War. Later this produktion was discontinued and the remaining parts were send to Nedinsco. I think Hans found this information in "CZJ einst und jetzt". Perhaps the date mentioned from Mike refers to this event.
However Norinab stayed as agent for Zeiss products in Sweden. I have found a lot of documents in Swedish arcives from the time of the second World War with the Norinab logo on them. The firm also represented a handfull of other German firms in optics and fine mechanics. I can present a detailed list later, I don't have this material with me here in Sweden.
