Binocular List #100: 15 April 2000. Aberdeen, J-list, Reicherts

==================================
Subject: Aberdeen Proving Grounds, U.S. Army Ordnance School

From: Peter Abrahams

In my bookshelf I found a publication from Aberdeen:

U.S. Army Ordnance School, Aberdeen Proving Ground, Maryland. 'Elements of Optics and Optical Instruments', September 1959, ST 9-2601-1. 71 pages. It is a simple, general text, with nothing on binoculars, but it does show that the ordnance school did have an optical facility.

There is an unusual binocular that was sold with the note that it came from Aberdeen. It is 15 power, but not so marked, and has 70 mm coated objectives mounted on long extensions. It is built on a Mk 21 body (B & L or Kollsman 7 x 50). The only mark is 3554-L, on both eye pieces. In addition to eye piece focus, both objectives can be focused by rotating, a groove is cut in the barrel to engage a screw through the objective cell. There is a third hinge between the objectives. This binocular is very well made, with a fitted wood case. It now belongs to Bob Bibb and can be seen at:

Needless to say, any clues about the origin of this binocular would be greatly appreciated.

==================================
Subject: The J-list

From: Peter Abrahams

In 1979, Bill Beacom wrote to the Japan Binoculars Export Promotion Association in N.Y., asking for information on imported binoculars. They referred him to their Japanese home office, who sent a copy of the JB list discussed in list 99, in the Japanese language. The paper was folded, and several names were creased & illegible, which is why we have no 65, 66, and 209. There is a small college for Japanese students nearby to Bill, where a student was found to translate the text. This is the copy that has found wide circulation among collectors and is now posted on the web.

These J marks are usually found between the objectives, but are also found on the prism plate, visible through the objective.

==============================
Subject: Question on the Reicherts

From: Peter Abrahams

Robert & Elsa Reichert found a compact binocular called the 'Mirakel' at a German sales show in 1923. They imported it to the U.S. and began their Mirakel company of Mt. Vernon, N.Y., which included a repair shop with a collimator designed & built by them, and which offered lens coating just after WWII.

The Reicherts manufactured a binocular: computed the optical system, designed the instrument, produced the optics and body, and sold the product.

What were the name & specifications of this binocular?

Do we have any list members who knew them & can tell us something about them?

=============================
Subject: 100 lists

From: Peter Abrahams

We now have 100 lists, and when printed out in small fonts & no margins the total is about 180 pages. The list was the basis for the first US meeting of binocular collectors. There are 75 recipients, from Australia to England, France, & Italy. Contacts at ebay have brought in 20 or 30 of the members. Apparently very few of them know how to type, but that's OK. There's always the next 75 members & the next 100 lists. I've had some feedback to my griping & most of the respondents like the low noise & absence of idle chatter.

I belong to 8 email lists about telescopes, devoted to these topics: Astro-Physics, Questar, amateur astronomy scopes, telescope making, very large telescope making, buying & selling, large Dobsonian telescopes, and the history of the telescope. There are others as well. Not to mention the history of astronomy list & the scientific instrument list, which are quite valuable.
