Osaka Work Compass

I have this Osaka compass and know nothing about it says "Nunotani Seiki Seisakusho CO." And "Osaka Work" on the face of the compass but that's it. There are some numbers on on the metal circal around the face 5695. It has no badges with sereal numbers. It has a lightbulb in the bottom little sliding doors that cover the bulb when you turn a knob. I would love to know how old the compass is if it's military and maybe the value if possible. Thank you for your time.
