Dear Mr. Kuenn,
Thank you for posting your request on History Hub!
Military records in the custody of the National Archives do not include the record of assignment and operational activity of individual pieces of equipment. Under normal War Department and Department of the Army records management procedures, such documentation would be destroyed after initial administrative use.
We searched the National Archives Catalog and located numerous references to binoculars during the 1910s in various record groups that might be of interest to you. These records will not provide the information you seek about the individual who was assigned the binoculars you own, but they may provide some historical context for you. Some of the records have been digitized and can be viewed online using the Catalog. If you would like more information about any of the non-digitized records, please contact the NARA reference unit listed in that particular Catalog description.
Due to the continued impact of COVID-19, you may experience a delay in receiving an initial acknowledgment as well as a substantive response to your reference request from a NARA reference unit. We apologize for this inconvenience and appreciate your understanding and patience as we balance mission-critical work and the safety of our staff during the pandemic. Please check NARA’s web page about COVID-19 updates for the latest information.
The National Museum of the United States Air Force has some information on their website about World War I Binoculars that may be of interest to you, and the Naval History and Heritage Command also has some information online about WWI Era Binoculars with Case. The Smithsonian’s National Museum of American History has information about Prism Binoculars as well that may offer you some insight into the general history of your own binoculars. You may also wish to contact the National WWI Museum and Memorial for further assistance.
We hope this is helpful. Best of luck with your research!
