Interesting,
Unfortunately I can’t give you a good idea of the value. What people will pay for a collectable antique, I couldn’t guess.
Value as a usable sextant, not much.
It’s a nice looking vernier sextant probably pre war,
Unfortunately the most most important part appears to be missing, the test certificate with name of manufacture date, and errors.
If this was present it would be worth way more, probably as suggested over 1000.
Good point, actually, it’s not been kept polished, polish wears away the scale,
What the
Ohio means? Who knows, a ship called Ohio or owned by a guy from Ohio.
Interesting, I don’t think I would bother to bid without the certificate.
Might be worth your while taking it to expert, who could identify more info.
As stated earlier, it should have a number engraved into it. Which would match the test certificate. Along with a manufacturer or Brand Name.
The Brand name and no would give a good idea of when made.
