  1. 1532 is a Radio Frequency signal generator.
    1534 is a gas turbine rotor.
    1535 is a typewriter stand that is missing the flat "top" that the typewriter sits on.

  2. I agree with 1534 and 1535.
    I think 1536 is probably a starter pistol that starts an electric timing system.

  3. 1532 -- am radio receiver



    1532 -- I don't think that it is a rf generator (it has a set of headphones attached, which would be useless for a generator), possible a wide band receiver. The frequency is indicated in hertz, not cycles, so it would be after 1960ish also looks military, so probably Vietnam era


    I agree with the gas turbine rotor and typewriter stand.

  4. 1531.
    Maybe the tiny circuitry for a "talking" toy, greeting card, etc.
    1536.
    Heavy brass construction and markings hint this may be an arming and firing control for a large naval gun (cannon), maybe Japanese.

  5. 1532 might be a hearing tester.

  6. 1531 looks like a "bug" to me.

  7. 1531: Hand-constructed device designed to be small. From who does that sort of thing and the visible components, I guess it's an amateur radio transmitter, or receiver.
