The following list of abbreviated markings is of [mostly] Japanese optical companies involved with binoculars and identified by my research. Some abbreviations are found written, and some appear within logos. Keep in mind the abbreviation could represent Romanji, Anglicized, or the company with an earlier name. This resource is also applicable to telescopes, spotting scopes, microscopes and similar products. This is based on documented logo ownership and other period documentation and is NOT speculative AND NOT based on opinions. |
