Sankyō Kōki may have supplied lenses to the Tōsei Kōki company, before the use of the Komura brand: a Semi Frank has been observed with an E. Chibanone lens (a curious spelling variant), and Chibanon or Chibanone (チバノン) lenses are advertised on the Copenflex and Sanon Six, as well as another lens perhaps called Chibar (チバー) on the Sanon Six II.

Notes
- ↑ This advertisement dated 1954, reproduced in Shashin-Bako, gives the name "Chivanon" in Roman letters, but this is probably a typo.
