Are those Kamakura? They make the Alpen and the Brunton and the Fuji 14 x 40 stabilized, and the Nikon 14 x 40 stabilized, and the Captain's 7 x 50(not roof prism), as well as the second team Fuji 7 x 50 and the military version of the same. Most of the Japanese binocular industry is defunct. Kenko survive. Canon seem to be Japanese. Vixen also, and the big Fujinon mounted ones. One wonders If Japanese parts are assembled in China, vice-versa, or a mix. Probably some are all-Japanese, others all Chinese . Some models are assembled outside those two countries. I wonder about the phase coating on the roof prisms: is it a dielectric stack, or just a silvering/aluminization, or a combination?
