Let me get this straight Sloppy. Are you saying that compressed air was ejected through the blue nozzels rather than rocket eflux and therefore there would never be signs of heat discolouration
If so, this thing could have been fired and the blackening at the rear could have come from the electrically initiated flares.
As you can imagine I am still desperately trying to establish a likely reason for it lying where it was found.
Bear in mind it is roughly 12 miles from Otterburn.
Can you advise me of the significance of the dual coloured circle at the top r/h of the casing. Does it give any clues ?
