good evening everyone


a bit of a challenge now..


I have a plate that was fitted on Lancaster ME685 (squadron 207) that exploded over Toulouse on 5 April 1944.
I have copied the numbers/letters as I could see on this plate.
Some were mangled as the shock damaged the plate, so I did the best I could.
Could you help me determine what was this plate for ?
Thanks
GC
