Very Rare C. Plath Early 20th Cent THREE CIRCLE (Dreikreis) QUINTANT/SEXTANT
 

Rare three circle quintant by C. Plath, Hamburg, Ca 1900
 

Presented is an antique quintant, meaning a sextant having a range of 144, or an arc of 72. It was made by C. Plath of Hamburg, Germany, around the Turn of the 20th Century. It has one of their rarely seen three circle (Dreikreis) frames. In fact, this is only the second of this type that we've offered for sale making it ideal for the serious collector. See http://landandseacollection.com/id136.html It comes with a star scope, a collimation scope and a sighting tube for shooting terrestrial objects.

Based on our proprietary register of C. Plath instruments' serial numbers which dates back to 1895, and earlier if we include those made directly after Plath's purchase of the David Filby company in 1862, and the inclusion of a similar three ring design, but with micrometer drum in a 1902 catalog, we date it to be Ca 1900 to 1912. This compares favorably with serial number 7777 which, four years ago, we estimated to have been made Ca 1910 to 1918. That one was originally made as a surveying (Vermessung) instrument without shades (filters) and was purpose built to measure angles both on land and at sea, for doing surveys, making nautical charts or setting navigation aides. This is established by its arc which reads to 150 degrees rather than the customary 120 degrees for a sextant. Instruments designed for this purpose were not fitted with shade glasses so the ones installed here were fitted later as was the micrometer drum. This is not so with this earlier example which clearly was made as a vernier quintant with shades.

        SN 6270 over early “Stick Man“ logo
    Adjustable rising piece. A worthwhile feature
         Horizon mirror has one cracked shade
                    Perfect index mirror
CONDITION: Except for a few minor faults, the quintant is in exceptionally fine condition having about ninety five percent of its original lacquered, mid-night black, finish remaining. The same holds true of the original varnish on the three telescopes. It shows very little corrosion of its bronze parts and elsewhere it is in like new condition. The index mirror is clear, sharp and without blemish. The horizon mirror shows the affects of salt spray. The interior horizon shade is cracked, but tight in its frame and still usable. The tangent screw shaft has a slight bend, but is functional. The Ebony handle provides a nice contrast to the metal work. The mirror adjustment tool is a replacement.

The bronze arc is calibrated -5 to 155+ degrees with a vernier that reads from the right, from 0 to 1 minute of arc, and can be estimated to one sixth minute. Serial Number 6270 is imprinted to the right upper side of the arc and just above an old style “Stick Man“ logo which Plath referred to as their "Sun Shooter" trademark or "Sonnenschiesser" in German. Normally, you would expect to find that on the arc's left terminus. The sextant has four index shades and three horizon shades.

THE CASE:
The instrument is housed in a fitted wood carrying case with brass hardware. There is no key for the lock. Inside is a plate with the Plath logo and an address at 25 Stubbenhuk 25, Hamburg. The case is in excellent strong condition with a nice patina of age to its varnish finish. There might be a rag or a brush missing. 

This is only the second C.Plath three circle quintant/sextant we have ever seen. They are not even pictured in the definitive work on the topic of sextants, "Taking the Stars" by Dr. Peter Ifland. It will make a rare addition to an important collection or as a gift of importance.

OUR QUALIFICATIONS: We are one of the few company's still selling navigation instruments that know anything about them. For purposes of judging whether Joel's opinion counts, he was the editor of the chapter on sextants of the 1977 Edition of "Bowditch", The American Practical Navigator, NAVPUB 9; a member of the U.S. Naval Academy Navigation Symposium Board, 1975 -1978; the author of a book on marine sextants, Cornell Maritime Press,1975, and the founding president of Nautech Maritime Corporation which partnered with Tamaya of Japan in the introduction of their sextants and the famous NC-2 navigation computer, in the U.S. market. Joel is also a retired Master Mariner, and held a U.S. Navy "D" Qualification as a Senior Skipper - Oceans. From 1995 through 2000, he served as a Varsity Offshore Sailing Team coach at the U.S. Naval Academy.
 
 
This quintant is an outstanding example of an elegant Plath three circle frame model and rates 5 Plus Stars.
