A (US) veteran and I, are searching for more information about a Junkers 88 Luftwaffe plane. Another veteran brought an identification plate back to the states after the Junkers 88 was shot down.
We are now looking what information this plate contains.

I don't have a picture of the plate yet.

This is on the identification plate:
JU 88

Thanks in advance.
