Help with bomber relic

[michel]

Hello all,

I just obtained some type of escape hatch. The guy where it came from told me that it most probably originated from a B-17 crash.
I did some research but couldn't come up with any material identifying the aircraft part.
The seller told me that there previously had been a tag attached with the words Emergency Exit. Unfortunately the tag has been lost over the years...

Anyway, I was hoping that anyone of you was able to help me identify this aircraft part.
The hatch includes 6 small windows which are made out of plexiglass.
Here are some photos for your interest:









Hope to hear from you!

Thanks,
Michel

P.s. does this forum include any sub-forums where these kind of questions are more appropriate?
