This Exceptional Sextant Has Been Sold. Thank you! C. PLATH NAVISTAR CLASSIC TWO SCOPE SEXTANT Ca 1991  RARE PLATH WHOLE HORIZON MIRROR We are the premier source for all versions of the Plath Navistar premium sextants, including the “Royal” and “Traditional” and have sold more than any other dealer in the world! This is the first example of this type sextant we’ve seen even though it was introduced by C. Plath in 1991. It is in brand new, never used flawless "Collector Quality" condition. It was previously owned by a first officer for the Royal Caribbean Cruise Lines who bought it,and then never used it. He purchased it with the 6 x 30 prismatic Sun telescope and we have added a new 3 x 26 Star scope to complete the kit.  The difference between this sextant and other Navistar Classics is that it is  fitted with over size mirrors, and the  horizon mirror is rectangular and a “Whole Horizon” type. It also has the least non-adjustable instrument error of any Plath sextant. This is the 15th Navistar we've offered. In our opinion, they are the finest of the contemporary sextants. They will be equally desirable at sea or in a collection of only the finest, and should only appreciate in value. This Navistar Classic style was one of the last high quality models Plath introduced in 1990, just 11 years before their sextant production ceased. Don't confuse this sextant with the Navistar TRADITIONAL or the ROYAL, which we  previously discovered and sold. This is the first of the CLASSIC variant we have seen. New, and exclusive "state of the art" design features: Nonadjustable instrument error of < 8 arc seconds Updated ladder style frame  Lever action tangent screw release Oversize mirrors with Whole Horizon Adjustable vernier for “0“ index error Miniature batteries and light emitting diode Adjustable Makrolon handle for ergonomic fit  Presentation grade lacquered case deluxe brass campaign fittings DESIGN FEATURES: This Navistar Classic, is the equal of the Navistar Royal in Plath's line of premium sextants and was made in limited quantities to the same degree of non-adjustable instrument error of 8 arc seconds thereby putting it in the same class. Because it was a new design in 1990 with many advanced features, it sold for more than other sextants. The visual clues are the flat index arm with diode lighting, and the special micrometer drum with a rotating vernier, and Navistar brand imprint. The rotating vernier has six indents and reads to 10 seconds of arc. You turn it to match the "0" point with the "0" on the micrometer drum so that index error reads zero. It comes with its original detailed instruction booklet, with Plath certification and the number 64628, but no date. C. Plath quit producing sextants around 2001. The parent company has completely liquidated everything including machinery, equipment and spare parts.                    High impact absorbing liner with compartments PROVENANCE: Purchased by a Royal Caribbean Lines first officer, and placed in storage.

Plath Navistar Classic sextant with a rectangular horizon mirror that we have ever seen and is suitable for a collector or for use at sea .

As a result WW II, C.Plath was dismantled completely by the occupation forces. Around 1950, various prohibitions were lifted, and C. Plath was allowed to begin production again of sextants and other nautical instruments. Also in 1949,C.Plath was offered a gyrocompass patent and in 1951 the first gyrocompass designed to this patent was presented to the public. C.Plath progressed from the role of instrument maker to that of a modern marine navigation equipment manufacturer. In the following years the product range was expanded by many more modern designs such as autopilots, speed logs, radio direction finders, etc. In 1962 C. Plath was acquired by Litton Industries, a large American concern.The C. Plath North American Division was set up in 1978 in College Park near Washington. 1996 saw the introduction of the world's first fiber-optic solid-state gyrocompass by C. Plath. The first ever gyrocompass with no moving parts. Sperry Marine was formed in 1997 with the combination of C.Plath, Decca Marine and Sperry Marine with more organizational changes yet to come. After 163 years, C.Plath changes its name to Sperry Marine in May 2000. In 2001 Sperry Marine becomes part of the Northrop Grumman Corporation.     C.
