World War I German Trench Periscope

This is a World War I German Trench Periscope. This periscope is in good condition overall, and is half of the full set of “Rabbit Ears” that would have been used in addition to a mount. This piece still functions well and the glass has not clouded or yellowed from age. Additionally, it is in a condition where it could be remounted with the unincluded portions and used as it was intended.
