HARLING NAVAL PROTRACTOR PARALLEL RULE ROLLING BRASS BOXWOOD DIVIDER BOX VINTAGE Description

High quality brass and boxwood rolling parallel rule, circa 1930

Made by and marked

W.H. HARLING 117 MOORGATE LONDON

marked with owners name G.R. HEPPEL

Differs from the standard rolling rule in that three edges are set as a protractor, a design invented by W.F. Stanley based on the suggestions of steam ship captains of the Orient Company, known as a 'Naval Protractor', for laying down a ships course.

In very good condition with no splits or warps, the brass tube tarnished from handling, would clean up, a small rub to the edge (see last photo).

In original fitted mahogany box with brass screwed edge lid and base, paper label in the lid with a list of deviations from a specific ships compass.

With associated brass dividers.

Gross weight 887 grams.

Guaranteed old and original.
