No, that looks like a passenger seat for an Avro XIX – I have one myself that I keep tripping over.

2 Z3017 is a plausible Avro part number for the lap strap (item 2 of assembly Z3017).

Yep, believe nothing. Still don’t know what it’s off though. Could be a bottom panel or maybe an overhead, also maybe second cockpit? Cutout looks like an altimeter or a VSI on the missing dial.

Or Car Paint thinners, I doubt IPA will touch it given failure with meths.

I get the impression that DH were quite daring with their structures to judge by the number and variety of disasters caused by total structural failure. I recall that the Comet windows were intended to be glued in place but this was changed due to difficulties with the process. The double row of rivets combined with the square-ish corners of the windows was about the worst way of doing it. Also worth remembering the Hawaiian? jumbo which suffered a similar failure in 1989 but somehow managed a landing held together by the seat rails.

The life of a Lancaster in flying hours was very short and some were lost due to structural failure, far more were lost due to accidents and enemy action.

I suspect that the Avro Lancaster is more a space-frame than a monocoque with the skins only lightly stressed and a much smaller hole up the middle. The difference with a pressurised aircraft is that when you blow it up like a balloon it inevitably stresses the whole skin circumferentially.

The Lockheed plant at Burbank comes to mind as one of the all-time greats here.

This is what happens when you let architects loose !

What an ugly pile of rusty scrap, fronted by a bus terminal. Doesn’t look good when compared with THE Bomber Command Memorial we have already.

three headsets of completely different design from one aircraft?

a picture of the headstamps (blunt end) will help here
