CONDITION: The instrument, its ivory name and graduated arc, and its hardware
is in remarkably good condition, with a nice patina of age is in exceptional quality overall. All three bronze legs are
present. Missing is a small ivory scribe, and inlaid ivory plate, neither if which were of much use. Both mirrors have long
ago degraded with the passing of almost 200 years. If desired, resilvering is inexpensive and available through most mirror
THE CASE: The "stair step, or keystone" solid oak case is in good solid condition,
with some age cracks and shrinking. There is a lock, but no key. This style case went out of use by the 1820's -
40's and is a further gauge of the sextant's age. A label on the inside reads Charles F. Helffrich, Instrument
Maker, Sign of the Quadrant, No. 122 South Front St. Between Walnut & Dock, Philadelphia.
All in all, a highly desirable and worthwhile
example from one of the better known English instrument makers.
