The rivets on the clip, 6th photo down are clearly identifiable as AN430ADs, US hardware. Can you see any numbers on the door?
Unfortunately Flyboy the British AGS round head rivets are the same shape and I have no doubt the French and Germans had almost identical rivets.
Thank you very much MiTasol for your extensive explanation !
It is very possible that the seller lied to us, although we also bought from him two oxygen tanks which he claims that were recovered by his father from the same crash location during WW2.
I am attaching photos with one of them, although I doubt that it will help much, another thing that we are considering is that this hatch was recovered from one of the nearby airfields, Targsorul Nou, which was used by the germans, romanians, and russians after 23.08.1944...so that will extend the search further.
Great Info and discussion! We might also consider that these fasteners might be specific to the manufacturer (as we're leaning towards a B-24, Consolidated). I know manufacturers do make "unique" hardware (Lockheed Tri-bit screws for example) perhaps these fasteners may fall into this category.Because the head shape is inconsistent I lean strongly towards the British Chobert rivet OR SOMETHING SIMILAR where driving the plug/pin in completes the head formation. You will see that the first two from the right have almost parallel sides and the third has a distinct taper as would happen if the plug/pin was not fully set. It is possible they are Dupont or other explosive rivets and that the one on the right did not fully form but my gut feeling is that this is not correct
