Hi, Denes

In my opinion, You cannot state from a photo that has no visible date or WNr of the aircraft that it is an E-3 or E-7.

There are several reasons for this:

- Numerous E-3's were upgraded to E-7 standard, and thus in fact became E-7s

- A few E-7's (identified by works number) have been identified with the early type cockpit glazing.

- Also, I would suppose that E-3's did exist that had their engine changed and a N engine installed, and the cockpit hood exchanged with no official E-7 conversion data plate

So - it's an E!

Much of the reason for this is of course that repaired, converted and refurbished E-series aircraft were used to the end of the WWII

Regards,
Andreas
