The Yashica is their first model with this mount - it is a slightly modified version of the Pentamatic S, which had a bayonet lens mount. Yashica followed Edixa in their version of M42 - a Pentax lens fitted to this camera has the focus index mark just past the 12 o'clock position.
The Hanimex at the front was made by Petri, and the one at the back by Chinon or Cosina.
