Hhhhhhhhmmmm.... not public domain until this is proclaimed or pass some time. This is not German image but image bellong to some Czechoslovakian who made this after the war. This is my opinion. Web is designed to share knowledge but minimum of respect is to place credit when you use material.
Your opinion is interesting- is the number on cowling the reasoin you think that this is trainer unit? For me this is very interesting image. If somebody find site and link, you will see a great number of amazing images.
