Art Scale Kit A48065 1/48 WWII Japanese Gun Sight Type 98 (3pcs in 3 different sight variants)

Japanees 1/48 gun sight Type 98 in three different sight variants.
The Japanese Type 98 was a reflector-style gun sight used on many Imperial Japanese Navy and Army aircraft during World War II, including the A6M Zero.
Instead of a simple ring and bead, it used a collimator lens to project a reticle (a aiming pattern, often a crosshair) onto a transparent glass screen. This allowed the pilot to see the aiming point and the target at the same time, without needing to focus their eyes back and forth. This design made aiming faster and more accurate, especially in a dogfight.
