|
|
|
|
- Hughes-Owens version of Hemmi 152 and Post 1459.
- Post sold this model from 1932 until WWII.
- Hughes-Owens had this in their catalogue from 1935-1937 and 1948.
- 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.
