and broken.  There is black leatherette covering on the bino housing, with slight wear on the metal objective lens rings. The optics are in moderately good shape, clear, but not perfect.   The eyepieces are individual focus, with hard plastic rings, no sign of rubber eye cups or any way to mount them.  The right eyepiece has a military reticle.  The prism on that side shows a small spot of deterioration.  Looking in from both ends, the mountings and prisms and lenses otherwise look clear and serviceable, but are not coated.  The left hand prism housing plate has an engraved hammer and sickle device with two pentagon shaped symbols below to each side.  There is a number (possible serial no?) N55xxxxx (don't have it right in front of me at this time).  And below that, the number " 1940r " all engraved in white.  On the forward side of the forward hinge brackets, the number "7" is stamped on both brackets.  No other markings on either the binocular or the hard plastic case.  There is a cushion of rubberized material inside the top of the case.  

I have seen a pair of similar 6x30 binoculars listed on the web, in very bad shape, with a leather case.

Are these possibly East German/Cold War era, rather than Russian origin?  Would it be plausible to assume the number, "1940r" might be a pattern number, rather than a year of origin?  Who has more information about such binoculars?

Subject: Journals from 1930

From: Peter Abrahams

I found a couple of interesting British articles from 1934 & 1935.

Coutts, W.B.  Optical instruments.  Physical Society's 24th Annual Exhibition.  Journal of Scientific Instruments 11:2 (February 1934) 62-64.

"Messrs NEGRETTI & ZAMBRA exhibited the compocular which is a 6 x 30 prismatic binocular carrying a 2 in. liquid prismatic compass on the right side of the upper plate. By means of a subsidiary prism system about 30 degrees of the compass card can be seen in the field of the right eye-piece."

Coutts, W.B.  Optical instruments.  Physical Society's 25th Annual Exhibition.  Journal of Scientific Instruments 12:2 (February 1935) 56-59.

"Telescopes and Binoculars of improved type were to be seen on the stands of Messrs HENRY HUGHES & SON, LTD., Messrs W. WATSON & SONS, LTD., and Messrs WRAY (OPTICAL WORKS), LTD. The latter firm exhibited the “Raylite”, a new 8 x 30 model with a field of 8.7 degrees and exceptionally light in weight.

The most novel binocular in the exhibition was to be seen in the research section. This was the cleanable prismatic binocular devised by Instructor-Captain T.Y. BAKER and Mr J.F. SUTTON of the Admiralty Research Laboratory, in which all elements can be removed for cleaning and replaced without affecting the adjustment for parallelism. The development of this instrument should be of great service to users of binoculars who reside in hot and damp climates, where binoculars seldom remain clean for reasonably long periods."

Martin, Thomas,  The British Optical Industry in the War.  Journal of Scientific Instruments 23:2 (February 1946) 21-26.
