WWII U.S. Navy Gun Camera

[lfwises]

Good afternoon Gentlemen.  I'd  like to tap into your expertise concerning a WWII gun camera I bought on eBay 10 or 15 years ago. I've never been able to test it so as far as I know it's a non-functioning wall hanger. What I'd like to know is what type of planes would it have been used in, where it might have seen action, and  any other info you might be able to share. Thanks in advance for your help.  Steve 

P.S. I'm not familiar with your new web site. Could you tell me where to find the photo reducing software? Thanks again.
