The company Tōkyō Kōgaku Kikai K.K started out in Japan in 1932 as an optical company. At some stage it was integrated with the Topcon Company. The company’s history with regard to the manufacture of survey instruments could not be determined. A label on the case shows that it was overhauled and tested in 1973 so it was likely manufactored several years before then.
