The Sextant Box
Analysis in Fiji in 1941
The sextant box found on Nikumaroro and shipped to Fiji in 1941 had two numbers on it: 3500 and 1542 [link needed]. TIGHAR has recently found a plausible explanation for those two numbers. The first is likely to be the maker's number; the second a number inscribed on the instrument when it was calibrated at the U.S. Naval Observatory.
Fred Noonan loaned a naval sextant to a student of his prior to the fatal flight. That sextant box is extant and also has two numbers handwritten on the bottom of it: 3547 and 173. But the sextant inside the box is a Ludolph with a different serial number.
Sextant Box Numbers: Suggestive Patterns
This chart is organized in the order of the Navy number given to the instruments by the Naval Observatory when they were sent there for calibration. Two entries are theoretical; the rest are actual pairs of numbers obtained from various sources. Click on the funny symbol next to the headings to sort on the values in that column.
