Mystery Belt Fed Machine Gun Top Cover

Nearly there. I will hopefully soon move onto the dismantling phase which will begin with a long soak in penetrating oil. I was pleased to find (when I gave it an experimental tap with a plastic hammer) that the extractor spring is still strong.

Probably a long shot, but could anyone point me towards some info on how it comes apart? I am aware of a scan of the WWII German operator manual available online which contains illustrations of it taken apart. This is very helpful, but it isn’t quite a dismantling guide and still leaves some guesswork.

PS. Has anyone apart from me spotted the aviation themed serial number? The first flight of the Boeing 747 was in 1969.
