After some googling I found out it is a pair of binoculars made in the inter war years by "Ruhnke Optik Rathenow" (Rathenow being the place where they were made), haven't found how rare this one is, but apparently the Noctovist 7x40 is really rare, this is probably a more common model in a more common specification (8x30).
Ruhnke was founded in 1896. In 1920 the factory had 200 employees.
