More RAF Llandow scrap bits

Took advantage of the nice day this holiday for a trip out to the scrapping fields at Llandow. haven’t been for a couple of years, to my shame. In the intervening time one field has been sold and another’s owner was in prison, as of that morning. His wife was understandably in a bit of a state. Bumped into a third landowner who remembered playing in the aircraft as a child. One child would sit in ‘a small one’ while his friends rocked it around! Disappointingly he hadn’t collected any souvenirs. Most detector readings were pipes and skinning but there were a couple of identifiable (hopefully) bits. The square panel is fuel filler cover part no. 124 D 3470 7856P with an HFD inspection stamp. The piece with holes looks American and has the prefix 416 and an elongated capital D inspection stamp, as do the stainless drain plugs which suggests Douglas. I can’t find the big part number list to compare. The previously posted Boston pic was taken a couple of fields away from where these bits were found. On the way there I was treated to the retiring C130Ks putting on a show before a final landing at St Athan, thanks to baloffski for his post, or I’d never had known it was their last day.
