Item NA19 - Navigator’s Parallel Rule
This
large size (24”) parallel rule is made of boxwood, with brass plated copper
hinges. The edges area marked with protractor degrees on the top, and compass
headings on the bottom. There is some loss of original finish on the boxwood,
and the upper surfaces of the copper hinges are devoid of their original brass
finish. It is marked, “Harling / London” on the upper rule. This is W.H.
Harling, who made drafting and nautical instruments from 1851 into the 1900s.
The rule is straight and square, not with the parallax as seen in the photo.It
is a nice old rule that is quite decorative. Good+
