This is an "Astronomisches Rechengerät" made by Zeiss during WW II. You can
find a detailed description by David Charlwood in the "Navigator's
Newsletter" No. 76 (Summer 2002), p. 10 - 19. Its successor, the ARG 3, was
still manufactured in East Germany in the 60s and its use taught in the
standard East
German manual.
The price of the item on ebay is outrageous in my opinion; a similar item
went for less than 200 Euros a year or 2 ago (though that was underprized, I
think). If you want to have a look at one visit the Royal Navy Submarine
Collections (shelf No. Q35/27/84). The NMM also owns one, but it is in
storage.
By the way, whatever happened to the Navigator's Newsletter? The last issue
I received was "Spring 2008" and never heard anything afterwards.

Hi
does anyone know what this device is and how it works? Not looking to buy
it, just understand it.
cheers
Roger
the ebay blurb is below:
Here's a rare 100% genuine WWII German ARG-1 (Astronomisches Rechengerat 1)
celestial navigation instrument by Carl Zeiss Jena. This late 1940's war
issue was first used by the
Luftwaffe, then after naval trials, adopted for
use in German U-boats. This instrument is part of a collection whose history
suggests it was removed from the long-range U-boat type IXD Ex-German U-873
that had surrendered to US Naval Forces sometime in 1945. The celestial
computer is in excellent used condition and is 100% original. Its body is of
Bakelite construction and its original electrical cord is attached. It has
an illuminated glass screen and there are four original bulbs located in a
small storage compartment within the original storage box (see picture). The
microscope eyepiece with adjustable cross hair is in great shape as
pictured. The box is sturdy in all respects however its age wear is apparent
in the pictures provided. There are two original paper labels affixed to the
inside of the box as shown. Please note the small storage compartment that
houses the four bulbs as mentioned earlier. There is no
manual or operating
instructions in this sale. The ARG-1 instrument has not been tested. Please
review the pictures provided for condition.
