I,m not betting my life on it but I reckon it,s part of the magazine trigger release.Looks real close to it on the drawing.And the silver(Aluminium)paint means it,s internal structure,not in the cockpit.The wear and tear would be from the erks shifting the magazines in and out of the wing.Did you get anything else from the dig??

Thanks for trying – the reason I was asking was I could not see how what appeared at first to be a cockpit related item and ended up where we found it – but your theory would explain it – from the mag reading & what we have found on the spot, I am pretty sure the 20mm is still in there.

We know from documents that the engine was removed, though it was reported as totally smashed. We are getting good mag hits on the main crater too, so hoping for some good finds – prop hub, U/C legs etc probably.

Have been waiting four months now for the permit & dig is set for mid July – so will report on it then. In the meantime attached is the result of last years dig on another MkV – BL585 😀
