This model represents the late configuration of the World War Two-era, British-designed Mk II reflector gunsight normally fit to most P-47 Thunderbolts, some P-51 Mustangs and P-40 Warhawks.
The model includes the mount for the P-47 Thunderbolt.
From aircraft-gunsights.com: "As the British Mark II Gunsight was considered better (bigger 3,5 inches aperture and better optical performance) than the standard the N-3A or B gunsights being supplied at the time, most P-47 and P-51B&C arriving in Europe and as many as possible P-40 were modified at Air Depots with the British Gunsight before being delivered to active units. Note that this situation later led to the order of Mark 8 Navy gunsights as a stop gap measure for the P-47... Later on, some 9th Air Force P-47 were also fitted with the Mark IIL Gunsight; basically a Mark II with a variable sight head used for low level bombing and rocket firing.
"Some 8th Air Force P-51D were also modified in Europe to use the Mark II. This is quite puzzling as P-51Ds were already fitted with N-9 gunsights at the factory and the N-9 was unanimously recognized as far better than the much older British Mark II."
This model does not include the glass reflector plate of the real gunsight.
