Identification of parts, Lancaster Mk.I

[Senemedar]

Hello everyone. This is my first forum post so please be understanding.
Fate caused that we managed to find the place of collapse of one of the fragments of the Lancaster Mk I airplane from the RAF 617 Squadron - "Dambusters".
Now the question from what part of the machine these parts come from, probably from the cockpit because the cockpit lamp switch was found. I am asking for help in determining what the other parts were, what was their purpose, location.

Can you post photos ?

I will add pictures gradually.

The nameplate, what I was able to determine from the pages below.
"5U/104 is a Pulsometer, electrically driven centrifugal fuel pump Type FB1, and is a type used on the Lancaster."

The second part which I managed to identify. The knob of one of the lamps located in the cockpit, hence the presumption that in this place the cockpit has just dropped. The rest of the parts are mostly aluminum fragments of various devices, installations and plating of the machine. The machine was shot down by the anti-aircraft defense during the raid over the target on the territory of Germany and now Poland

Such scale. Looking through the photos of the cockpit, I noticed a very similar (and perhaps this) scale. The scale in the cockpit fixed (attached - holes) under the cover. After the scale in the level moved the pointer - indicator, you can see it in the pictures.

The first element, probably comes from the plating of the plane, was fastened with the help of rivets. Painted only on one side in gray and the other side in pure aluminum. Has a serial number. It was not straightened out of the ground in such a state. This panel covering the camera is probably too small .. 21 cm.

I think it is a panel visible behind the red line. Will anyone confirm my suppositions.

The round panel visible behind the red line is made of glass and it is a kind of a window for the F24 camera. Your panel is of metal and IMHO it is a kind of accessing or inspection panel. My first idea it was one of the panels seen at the base of the rear gun turret. But there is more of them at all surfaces of the bomber. Additionally fuel tanks had the round inspection panels too. However most of them seem to be of six rivets ( screws ) while your one has ten holes. Also the colour is a little bit incorrect. If it would be a Lancaster it should be either of Dark Green or Earth Brown. In the case it would suggest it came from tops. Or if it would be of black it would suggest the sides and undersides.

The panel is painted gray on one side. Each of these parts has a numeric signature. Probably all were near the cockpit, if possible, please identify them.
