I need your help with this piece. I was told it came from a shot down US "fortress" /either B-17, or B-24/. The story is, that it is a hand crank dynamo, used to produce electricity for starting the engines. One thing for sure, it really produces electricity, it works. So, can you please help me, what is this thing? Is it really a WW2 aircraft part? Thanks!
