One of the more unique items tucked away in a drawer was a Vintage US Navy Sextant made by Keuffel & Esser.
- Date of Inspection...12/31/1942
- Maker... K&E (Keuffel & Esser)
- No... 0107
- Sextant (N)... No. No.
No. 0107 is engraved in two places on the box & 3 places on the sextant. The number refers to the inspection catalog by the US Navy. K&E New York 470 appears to be the serial number we found on it. Based on this number and the Keuffel & Esser Dating chart from Survey Antiques, we believe the date this was made is between 1887 & 1888.
Here's the rest of what I've learned....
Sextants are an instrument with a graduated arc of 60° and a sighting mechanism, used for measuring the angular distances between objects and especially for taking altitudes in navigation.
There were only a few sextant manufacturers that we've read about:
- Warney & Swasey
- Keuffel & Esser
- Buff &Buff
- David White Co.
- Keuffel and Esser Co., was a drafting instrument and supplies company founded in 1867 by German immigrants. It was the first American company to specialize in drafting supplies & drawing materials. In 1867 they began selling survey instruments. They made sextants and stadimeters according to U.S. Navy specifications in the early decades of the twentieth century. They ceased production around 1969.
