It is a Keuffel & Esser Co. Twisted Frame Standard Transit. Circa 1891. All functions are operative, Optics are very good. The following is a brief history and description of this Transit. Please see all 12 Photo's. The "twisted frame" and many other features of this transit were designed and patented by John Paoli, of Hoboken NJ while working for Keuffel and Esser. The main plate is marked "Patented Dec 3, 1889, May 26, 1891, Oct 13, 1891" and the celluloid compass face is marked "Keuffel & Esser Co., New York", Chicago. The serial number 2053. The reason for the twisted standard (in addition to aesthetic)and the method of its construction are described in Paoli's U.S. patent #453158. Many other attributes of this instrument are described in that patent and the innovative telescope is described in patents #416270 and 461389. These and all U.S. patents may be viewed online at the USPTO site. The 10" telescope has a top mounted object focus and a top mounted eyepiece focus, with a 6" underslung level vial. All three tangent screws are spring loaded. The two vernier windows are protected with hinged brass covers fitted with white celluloid reflectors.(The covers are missing) The arms of the leveling base which accept the screws are split and compressed with an adjustable screw to take up any wear. The compass needle has vertically flattened ends, curved slightly upward so as to function when the compass is not perfectly level. The brass has a uniform dark patina and is uncleaned, The white powder is the remains of some one trying to polish the brass with Brasso many years ago. This white powder will come of with a medium bristle brush. I have not done any cleaning I leave it to you. All of the level vials on the main plate, as well as, the telescope are in working order. The adjusting nuts are still present and the studs are 2 5/8" on center. The internal needle arrestor linkage is functioning, as viewed through the center hole in the compass face. All adjustments are in working order with and properly functioning focusing mechanisms. The telescope has no cross hairs. My reserve is $995.00. Complete with the original tripod.
