Original item: Only One Available. Measuring 19 ⅝ nches in length, this is a very nice WWI Era Model 1918 “Battery Commanders” periscope. In X 7.5 power, these were used to help view and plot artillery attacks from behind cover, to avoid exposing the commander to danger.

The optic came to us from the American Armoured Foundation, Inc. Tank and Ordnance Memorial Museum. The AAF Tank Museum was a living memorial dedicated to the Tank and Cavalry soldiers of the world. Before 1981 some of the artifacts that make up the AAF Tank Museum was a private collection belonging to Mr. William Gasser. Mr. Gasser felt that his collection would be beneficial in educating present and future generations to the sacrifices made and the technologies gained during war. Therefore, in 1981 the AAF Tank Museum was established as a non-profit charitable organization, and Mr. Gasser's donated his private collection to the Tank Museum. Mr. Gasser is still active as Volunteer Director and Curator of the Tank Museum and his knowledge of military history has been a great asset to the museum. Unfortunately after 20 years of operation it had to close its doors, which is when this sight was acquired.

The bottom of the periscope still has the manufacturer’s markings:

Still providing a good image, lens needing a good internal clean however but still usable. It actually appears that someone made an attempt at removing the housing, but as a result they broke two of the three brass screws holding it in place. The bakelite eye cup is still present, and in great shape, and the focus diopter works correctly.

Condition overall is worn, but the original paint can still be seen, even with the extensive chips through to the brass body.
