Aero Vintage Books

Hey guys. My wife deals in antiques and found a couple items I thought might interest you. The first is an A-5 Sperry Automatic Pilot, Spec # 27359. I have done some research, but not sure what the value might be. I enjoy flying, but do not have a b-17 or b-25 to put it in She also came across, what looks like, a radar dish Part #102973. Any help identifying these items would be great. We would love to keep them, but it would make more sense to sell them. Thank you.

I thought the B-17 and B-24 used the A-5 around 40-42ish??? I called MIT to inquire about the AP, since they had a hand in building it.

No pics of the A-5 automatic pilot yet.

Ideas on what these are and maybe a value. I obviously have no need for them. Thanks.
