coastal artillery badge help

[andya]

Hi
I have looked through all previous threads about this badge but cannot find one like it. Is this original and if so can you ID the maker. My concern is that this is a copy. Is it normal for the gun barrel to go out of shape like it has on this badge?
thanks

Yeah I'd have to say that's pretty normal. Erich

This is an original, Andy.

Andy, the barrel is bent like that in order to lead fast moving ships.
