Subject: Symbols on Japanese binoculars
I have and had some 15 x 105/60 deg inclined wtih the chrysanthemum symbol, and was told that that was Toyokawa Navy Arsenal, which after the war became Kowa, or part of Kowa, now Kowa Optimed in Torrance. There are dozens of Kowa 20 x 120 at Tokyo Tower, near the sword museum, same as the Israeli offerings in the DO catalog. Another 15 x 105/ 60 deg inclined I owned but traded was labled with a Star of David. That was the symbol of Enomoto Kogaku, which became part of Fuji Photo Optical-Fuji Meibo-Fujinon.
Subject: Reproduction head cushions
(from List 273: >superior copies of the 25 x 100 cushion for which I made a mold )
Yes, I still have the mold I made 30 years ago, and many sets of the aluminum supports I made to fit the 25 x 100 cushion copies to the Busch 10 x 80 with 45 deg. inclination. I may have one or two extra cushions, but it is time for a new production run: buy the liquid polymers, set up, and run off 50pieces or thereabout. If others are interested, that would increase my motivation. Environmental and industrial safety requirements have changed the availablity of some of the materials I formerly used, I believe.

improved optical and mechanical configuration markedly reduces stray light.
Leica's High Lux Sytem (HLS) - a special mirror coating enhancing the prism system that is applied utilizing an advanced Physical Vapor Deposition process generated by an Ion Beam and particle accelerator. Forty-three separate coatings are applied in a thickness as little as 40 nanometers. These so called lamba/2 coatings, which transfer 99.5% of the light over the mirrors, not only generate additional brightness, but also allow for optimization for only one wavelength of light.
