A small part with "ASS S205 1" marking on it

[gillescollaveri]

Hi gents
this small part was found in Normandy next to the big back panel (two threads before) and I suspect they originate from the same aircraft.
The marking is "ASS S205 1" and the stamp is "EEP 284".
Would this give a clue ?
Thanks

EEP 284 in a circle is an English Electric Preston inspection stamp. If this is a WWII artifact it is most likely from a Hampden or Halifax.

Hey gillescollaveri,

Is the material steel or aluminum? If it is steel then I am pretty sure the ASS S205 stands for Austenitic Stainless Steel 'S' series type 205. I do not have any idea what the 1 is for.

I don't think that part is stainless looking at the discoloration and surface scratches. Why put a material spec on an individual part while not including a part number?

Hi gents,
I don't know what material it is ,
I would be inclined to say aluminium (when I see how torn it is )
but I shall ask to the archeologist who has the part in hand. I let you know;
Cheers

It is also a kind of aluminium but quite thick and solid. For example, we cannot stretch it, whereas we can with the pieces of the fuselage.

Hey LouAMD,

What is the thickness (it looks to be about 2mm to my eye but it is easy to misjudge from a picture) and weight?

On an old post, a member posted photos of what was believed to be parts from a Halifax that used the same "ASS" prefix in front of the P/N

After enlarging the photo and inspecting some of the scratches and a little bit of surface corrosion, I'm pretty certain its aluminum.

It weighs 47 grams and it is 1-2mm thick for 14cm long.
Indeed, this other part is similar to the one that I have...
