It probably got lost as the reflector was made of sandblasted glass which not only acts as a diffuser, but even reduced the amount of light available. Finally the micrometer is illuminated directly and has a rotatable glass reflector, which sadly enough is missing on this T2 (see figure 3). The horizontal circle is illuminated by a prism at the base were later T2s would have a mirror (see figure 7). The vertical circle is illuminated by two distinctive prisms on two sides of the telescope (see figure 6), that are typical of this archetype T2. I will then post your offer in the thread without revealing your name.This T2 has sexagesimal circles divided in degrees down to 20 arc minutes intervals (see figure 12 and figure 13), can be read using a micrometer directly to 1" and estimated to about 0.1". Please post your offer to this thread unless you wish to make a private offer, in which case you can send me your offer in a message via this forum's message system. As of this posting we have a $300 offer for this instrument.

To access the description, images, and other related information, please point your web browser to The file named '05 Index - Wild T2 theodolite.pdf' contains the description of the theodolite as well as an index to the various JPG image files found in the same folder.Ī similar Wild T2 theodolite graduated in mils sold on eBay for $395 plus shipping in late February 2016. I used quite a bit of effort and research time in an attempt to make the description complete and the images informative, but if you have questions beyond what I provided please post to this thread or send me a message via this forum's message system.

Rather than burn up a lot of Wendell's bandwidth on this forum, I have posted a detailed description and more than 20 large images of this item on one of my download sites.
The optical-plummet tribrach has a locking lever (not a locking knob). The published accuracy of circle readings is 0.002 mils which converts to 0.41 arc seconds. The circles are graduated in angular mils (6400 mils in a circle).

Going by the serial number and the markings on the instrument it was manufactured sometime between 19. This instrument was orginally purchased by the United States Department of the Army. Among the articles on that site is a particularly interesting history of the establishment of the initial point of the Principal Meridian of Montana. Kent McMillan mentioned his colleague and friend Charles in several posts to this forum you can find those threads using the search function. Charles Swart was the founding president of the Montana Association of Registered Land Surveyors and had land-surveying practices both in Bozeman, Montana and San Marcos, Texas. I am doing this simply as a favor to Mrs. A while back I offered to help Charles' widow dispose of several survey-related items that Charles had accumulated through the decades. Therefore, this thread will replace that earlier thread for purposes of this instrument.
Having separate threads for each item will be easier those interested to follow the item and to keep track of offers as they come in. This is one of the five items featured in the thread I started on Monday 11 April. This instrument is in very nice condition and is something all you Eighty-Two Charlies need!
