David,
It's been over a decade since we last communicated, but in doing some research on an Me262 pic I was just shown by a friend, I stumbled across this thread and had to comment. I just was shown (and have a digital copy) a nearly identical photo to the one you posted. Same aircraft. Looking at the painted over side number, I'm fairly certain it is 13, not 3.
Drop me an email at
cobrahistorian@yahoo.com and we can talk more!
