So after reading the pilots notes for the F.1, F.2A and F.6 and looking at gunsight camera pictures it turns out the gun sights and event markers are all based off the Lightning F.53 So here they are corrected: F.1, F.1A, F.2, F.2A fitted with 'Pilot Attack Sight"   F.3 fitted with 'Light Fighter Sight Type 2 Mk. 2   F.6  fitted with 'Light Fighter Sight Type 2 Mk. 3   F.6 fitted with 'Light Fighter Sight Type 2 Mk. 3 and later service 'event markers'.
