    G'day all I have two instruments from a Japanese plane and was wondering if, from the serial numbers, I can find out what plane they were fitted to and where that plane was lost, ultimately finding out how my Grand Father came to have them in his possession as he was in command of the Adelaide during WW2?

    Hi OzFrog,

    In my experience, the serial number of the individual aircraft doesn't appear on the instruments fitted into it.

    Best you *might* be able to do is determine what type of aircraft it was, however in many cases instrumentation was standard. If there is any kind of manufacturer's plate/label on the instruments, you might have a chance of determining the aircraft type, but as noted it's not certain.

    Could you post photos of the instruments? Many smart people here who could identify them or point you in the right direction.

    Thanks for posting the photos. Are there any tags, labels, plates etc on the back?

    Thanks For the info, would both these have been in the same plane or are they likely to have been from different types?

    They're both Yokogawa instruments (bottom line, large characters). The lower one is indeed a Type 92 Model 2, so aozora's spot-on with that one. The upper one however is a Model 1 turn-and-bank indicator. I think I can see an anchor (=Navy?) inspection stamp on the right hand side, next to the screw, however what I can't see is the date of manufacture. That would have been stamped into the blank spaces in the lower middle row. The stamps would tell you year and month of manufacture,which might at least help you rule out various aircraft types. Can you tell us what the stamps in that row are?

    Gak, sorry, brain-fade, it's a Model 2, I'm guessing Navy due to the anchor stamp.

    You'd think I'd learn by now, one stick = 1, two sticks = 2.

    Re: the data plates: the top line is the instrument type; next line is serial number (stamped) Navy Anchor (stamped)
    3rd line is Showa (year - stamped) Month (stamped); followed by manufacturer.

    Neither instrument has a year/month stamped into the plate, possibly indicating wartime production? Because the instruments were common to most naval aircraft it would be almost impossible to know the aircraft type, but with their common manufacturer it is possible they both came from the same aircraft.
