The British Military Prismatic Viewfinder Compass is a valuable piece of militaria from the era of World War I. Issued by the Army in Great Britain, this compass was designed for navigational purposes during the conflict. With its prismatic viewfinder, it allowed soldiers to accurately determine their location and direction. This particular compass is a tangible piece of history that represents the service and sacrifices of those who served in the British Army during the First World War. I have not polished it as I prefer not to the switches on both sides are in working order and comes with the leather case. please note I cannot find any markings.
