Anti-Aircraft Sights on the Japanese Type 99 Arisaka.
The Type 99 Arisaka featured a unique rear sight system with a standard aperture and an adjustable ladder sight for ranges up to 1500m. It also included flip-down anti-aircraft wings designed to lead slow-flying aircraft at specific speeds. While innovative for its time, these AA sights became less effective against faster modern aircraft and were eventually removed for resource conservation.
