BF 109E and location of Werkenummers

[Lentomestari]

Messerschmitt BF 109E identification and location of Werkenummers

(Question is about planes main construction number, not part numbers etc.)

I ask some help and information about where to find all possible places BF 109E's have Werkenummers located - stamped or painted. First two places are obvious: main ID-plate and tail left side where WNr. is painted.

Except for the above - where other possible locations WNr. is marked?

Engine cover and gun cover hatches, are there WNr. painted/stamped inside those?

Landing gear doors, are there any WNr. stamped?

MG ammunition box - are WNr. painted in it?

Then one question about main ID-plate. What material it is made of. is it possible that it survives if plane is burned down?



Somewhere found this photo about BF 109E WNr.4034. I would want to know where this stamped Werkenummer is located? wings?
