Does anyone know what this instrument panel is?

Hello all!
I'm trying to identify this instrument panel. What it's for and what aircraft it's from. It's allegedely from the mid upper turret of a Lancaster but what would a bomb isolation switch be doing in a gun turret???
Any information will be much appreciated.
Thanks in advance.
Mark.

Nice find mate! Can you post a bigger picture of it, or write out what's written on it?

I haven't got it yet. Before i decide to get it or not i'd like to know what aircraft it's from. Sorry, but that's the only pic i've got. Regards. Mark.
