Thanks everyone for the conversation, I can confirm that the two boys in 1944 witnessed a number of crashes from their favourite spot on top of a pill box at Finchingfield, then they would ride there bikes to the crash area. 71 years later those memories merge but it would seem that it’s a 90% + reasoning this is from Dry Gulcher and will go to Ridgewell to add to the other pieces of that wreckage and story.
