I am not sure if I am replying correctly, but I was trying to say that this looks like a window assembly, of which I have a few parts. I wondered if anyone has a high res version of this page? Thanks, and sorry of I am doing this wrong; I'm new!
I have some parts from a P-38 that had crashed long ago. I have just downloaded this manual to try to identify some of the pieces. It is mostly in bad shape, but this will help a lot. Thank you.
