B17 Bomber

Hello. Need some help with identifying couple of parts. Long story short.. My friend from Poland have dug out some parts of aircaft and wants to find out what they are and is there any value in them. There is a story that a B-17 crashed in ww2 around that area so he suspects that that parts belong to it. I've attached couple of photos. Could you have a look and let me know what you think? Thank you.

Could that be parts of a Norden bombsight? I'm certainly unschooled in these things but if s/n plates say "bomb sight" and it's from a B-17 downed in WW 2, what else could it be?
