Here's a Google translation of a Japanese webpage
including information about the Walz Wide camera:
Camera name Waltz (sic) wide
Country of manufacturer & manufacturer
The japanese waltz trading company
Production years 1958
Shutter Copal B, 1~1/300 Lens [warutsua]
35mm F2.8
Olympus the point of popularity receiving the influence of the wide private
machine which is cut, if with the camera which was made, as for the body
you say that with the camera which was made relatively politely, there is
no feature it is the camera which is not.
Hope this helps... 😉
