Help please identifying ww2 aircraft parts found in the Vosges Mountains France

Daniel BASTIEN · Jan 13, 2020

Hello Has anyone any idea about these ww2 aircraft parts ? German ? British ? US ? and what type of aircraft ? Sincerely

If those numbers visible on one part are about 20-25mm high they will be part of the material specification. Please advise the material type (Al alloy, from the look of it) number height and if it is around 20-25mm I will check out the British and US specs to see what pops up. I do not have any European specs but others will.

Your best bet is to find numbers stamped into those short stainless parts. From those a fairly good identification can be deduced though with some caveats like 75-nnn parts can be B-17 or P-36/P-40.

If there are any inspection stamps (usually a letter or two with numbers such as below that will also help considerably. Douglas use a long D with a number inside.

The two below show acceptance by the US military. Other military's had their own equivalents

This one and any variations indicate the part was heat treated

Thank you MiTasol for these precisions Sincerely

Have you found any part numbers or inspection stamps?

Picture number two in the OP shows the numbers "040" - the number four shown looks to be more British or American as the Germans used a different font style in their numbering system.

Hello,
Here is another piece found on the crash site. It looks like a piece of the US 430M1 emergency warning horn, that could have been used as a stall warning horn or to inform the pilot of any other dangerous situation, to have the pilote react accordingly. GrauGeist was right. So, as the older locals remember the crash site as the one of a fighter aircraft, my guess is that the crashed aircraft could as well be a P-51 or a P-47. Does anyone know if this guess is correct ? Sincerely

MiTasol · Jan 25, 2020

No.
This is from a much later aircraft as part number MS25222 was first approved in May 1957. The equivalent part in WW2 would have the AN5776 part number. The contract number usually starts with the year the contract was signed so if you can read that you will have the earliest year that the part was built. It was probably fitted to an aircraft in or after that date but that is not an absolute.

Thank you so much, MiTasol, for your expertise Sincerely

I'd guess that "040" probably refers to the thickness of the material. The rusty hunk has what looks like a Bendix drive gear on the small end, which would be used with a engine starter.
