There is one more Bf-109E-1s that exists as well. It is in England. The wreckage was found in Spain but is an original Bf-109 airframe. It is currently being restored.
Also the Bf-109E-3 that is on display at the Deutsches Museum in Munich, Germany was actually a E-1 that was restored as a E-3.
I dont have any pictures unfortunatly.
