Hughes-Owens 1766 - Log-Log Twinplex - Notes



  1. Hughes-Owens version of Hemmi 152 and Post 1459.
  2. Post sold this model from 1932 until WWII.
  3. Hughes-Owens had this in their catalogue from 1935-1937 and 1948.
  4. Not sure if this model is pre-war however the Bamboo has turned a rich dark brown colour, the action is still very smooth and the cursor is the old style.
