We bought this at a garage sale & can't find anyone who can tell us exactly what it is. We've searched all over the internet, visited the local VFW, the Planes of Fame & the Air Museum in Chino, CA... nobody seems to know. If someone here can help, we would greatly appreciate it.
Thanks, Denise
cakollektor, could you give us the dimentions of the part. I have to agree with Thorlifter. It looks way to big to be for an aircraft. At least by looking at the pictues and the location for the placement of fittings.
Thanks so much to everyone for the input. In answer to Saburo's question regarding a data plate, there is none... we did find a number stamped into the metal underneath top ring. I wrote it down, but can't seem to find where I wrote it now. I believe it was six digits, the first digit a 3. It came in a wooden box, but I don't know if it is meant to be in the box, or if a previous owner did that. The top ring is 5-7/8" diameter & the height is about 4-1/16", not including the post that sticks out the bottom. I added a couple more photos. Again, thanks for the help. Denise
cakollektor = the lucky collector of the year !!!???
To me.....
This is a Japanese Reflector navigator's compass model 1 or 2, (kai ?).
According to my sources it could be Type 2 Kai (to be confirm !)
your compass is missing the reflector mirror (may be not, it was use as a simple aperiodic compass (like the British type P6, P8, P4, P10, P11)on the BETTY & FRANCES bomber), the lighting system,the card holder and the data plate (could have been a decal). A specialist could be more precise for the Type.

P.S. More and more I think your compass must have been used without the miror, for direct reading from above (like the Brtish type, see above) as the numbers are written in a normal way not reverse as they are on the document attached (to be read with a mirror) so I would say Betty bomber or Frances A/C.
Wow, this is a fun mytery. Do you have any assurange that it is military related at all? I mean yes, its got the look, but it might be some sort of flow meter for a milking parlor for all we know!
Based on the submarine theory and didn't see any obvious matches on the sttering equipment stations. But someone else might have more time -- and its a great site to look at in any case.
Does anyone else look at the -40 to 40 scale and the 10 to 0 scale and think some sort of main and vernier scales?
