Plath Sextant

<< >>
This has a blackened brass frame and a silvered scale that is graduated every 10 minutes from about -5° to +155° and read by vernier with tangent screw and swinging magnifier to single seconds of arc. The inscription reads "C. Plath Hamburg" and "2625." The serial number suggests that it was made around 1906. Captain Paul K. R. Salo acquired it in California in the early 1930s.
