It's a shame Dorissdad has not popped back here since. I would be curious as why he seeks this location and what sources he may have already tried?
If he does, it's worth highlighting the only rough location given for the spitfire crash is the vicinity of the paper mill. I wonder if the pilot logbook (possibly in family hands) gave up that information?
In the link I first posted, Swift to Battle, there is a further image of Peter Pool on the page following the account of his parachute descent. This image of him and Diana is credited to D.E.Pool, probably his wife Diana Eileen Pool?
