Yes the Eagle is not a simple emblem, painted in the tower. It is a 3D bronze plaque that was fixed there in PRE-WAR U-Boats. Once the hostilities started, the eagle was removed from all U-Boats as it was felt that with it the CT could be spotted and above all, the nationality of the UBoat identified easier.
Note in the picture posted in the first post that the U-Boat has also the number painted in the CT sides, a very giveaway indicator of it being pre-war.
Nevertheless, I concur in that the emblem is awesome, and -historical accurancy aside- it looks too damn good to simply let it go
