I'm not sure if this is the right place to post this, but someone responded to the ads I have posted to offer a log book of some type that they found in their grandparent's house. Apparently, it's some sort of personal logbook detailing air raiding missions over Japan. I don't have any interest in something like that, so I told the seller that if I found anyone with interest in that area, I would give them her contact information. It sounds like it may be a good research tool, but I really have no idea. If anyone is interested, please let me know and I'll send you the lady's information. She is local to western Pennsylvania.
