Vintage Military Army Trench Periscope 1952 Soviet Russian Polish Optical WW2

  

I really don't know much about this item other than what I have read on the internet. Original Russian or Polish trench periscope dated 1952. In good solid overall condition apart from missing the eye piece that screws on the piece you look through. Easy it is to get one of these so listing at a reasonable price to reflect this.

Measures 57.5cm long x 8.5cm wide.
