: Does anybody know the colors of the German G7
: torpedo in WW2?
: Most of what I have found looks like they
: were natural metal on the main body and
: fins, and the warhead section was a bronze
: color. Some folks say they were painted. I
: am not sure of that, and I know they were
: coated in grease while stored at sea, so
: paint seems like a non-starter to me. Any
