Very interesting to hear of your family connection. I think you mean KH546 for your uncle’s aircraft? Unfortunately I never got round to a site survey, though I’d be pleased to help on the metal detecting front if you could get the landowner’s permission –*I think you would be well placed to do this. I did contact the RAF museum, who sent me copies of the accident report cards, and some kind person also sent me an aerial photo that may or may not show the crash site. I’ll PM you.
