An exceptional, investment-grade piece of British Great War history. This prismatic field compass (1917)is presented in its original, heavy-duty bridle leather case, clearly stamped "R. Stafford 1918." Robert Stafford was a renowned leather craftsman of the era, and this case—built to withstand the rigors of the front line—has protected this precision instrument for over a century. The compass itself is in full working order, featuring a mobile dial and clear optics, the dial can be held static by a screw on the side when the compass is not in use. This is the perfect centre piece for a militaria collection or a high-end gift for a history enthusiast. It represents the final, refined equipment issued to British Officers during the closing year of the First World War. These were "Prismatic" compasses, meaning they have a flip-up prism that allows a soldier to read the bearing while simultaneously sighting a landmark. Highlights: Date: 1917/1918 (Final years of WWI). Case Maker: R. Stafford (Stamped and legible). Functionality: Fully operational. Aesthetic: The leather has a rich, dark "chocolate" patina that only comes with a century of age. Measures 9 x 6.5cm (3.5" x 2.56").
