[Trooper117]

The arrival of P-40E's with factory fitted sights, was the first 'official' aircraft with a correct integrated sighting system.. All Hawks had the ring and bead sight, however, the Group Adjutant, Charles Mott, had through CAMCO aquired N-3A optical gunsights that would be fitted to all aircraft in Burma.. The resulting problems from these 'in house' modifications were not ideal, but they were fitted non the less.. some pilots didn't get on with it and resorted to just using the ring and bead sight.. One of the problems was that the refector image was projected from the floor of the aircraft directly onto the armoured glass plate in the front of the cockpit.. Pilots soon found they would knock the sight out of allignment because they hauled themselves out of the aircraft by pulling on the top of the plate..
A hundred brackets were procured from a local British firm in Rangoon to make this mod available to all sqns in the group, so its perfectly feasible to have a reflector type sight in the old Hawk..
