I greatly enjoyed the review by Holger. These are 3 of my favorite binoculars. The IOR is available commercially with full mil equipment of infrared detector/ranging grid and without either. The optical performance is slightly better sans mil fittings-a bit brighter prob due to lack of reticle. My non mil version was made later as well. According to the US importer, the coatings of IOR are licensed Zeiss Overkochen coatings, not CZJ. They also make an 8x30 Deltrentis-like glass which performs as well as its progenitor to my eye; a very heavy but optically outstanding 10x50; a lighter 10x40 and a very nice but slightly large for power 8x21 which has been mil issue in GB and that has the unusual feature of bilateral individual eye focus plus central focus! This results in great near focus making it a wonderful glass for nature hikes,etc. The yellow tint has been discussed before but I must say that I find the 7x40 a great all day, all weather glass because if it. I am not a serious bird watcher, however, so absolute color correctness is less important. Also, after some use you filter it out mentally and don't notice it. It clearly was Soviet issue as well and appears in fig 82 pg 158 of Dr. Seeger's second edition so labled.
The mil EDF 7x40 has a most awkward IF filter system-you have to do gymnastics with the glass to get it in and out of action, and I have found the Docter version brighter as well.
The PZO has the unique rubber armour but and seems to be a unique design as well. I have a 12x50 PZO mil issue of the same era which is a more typical variation of a CZJ design and does not enjoy the same overall quality.
Just my 2 cents. Arnie

There is a very good review of early Nikon marks & models, mostly binoculars in the new NHS Journal:

A message from Wolf Wehran on some new binoculars:
Just back from a press meeting near Toledo with 20 journalists of the shooting + outdoor press in D, A and CH. We introduced 9 new rifle scopes and 3 new binos. These binos are a real pioneering achievement. For the first time their optical system has lenses of fluoride glass which permit an almost perfect correction of the secondary spectrum. An advantage which is visible. Fantastic contrast and colour rendering, no flare and no colour fringes under any lighting conditions. They have the designation "Victory 8x42 T* FL" for instance. FL stands for fluorite glass, as in our spotting

My name is Steve Cather, and I would like to join the binocular list. I am a professional geologist in Socorro, New Mexico, and have had a long interest in optics, in both their use and repair. I have a question for the list members. I recently bought a 20x120 U.S. Navy binocular at a pawn shop in Gallup, New Mexico, for quite a reasonable price. They are, I believe, the Mark I, Mod 3 type
