Wonderful Circa 1854 Burt & Bailey Solar Compass – Yosemite

By The Compleat Surveyor

Comments Off

This is a really neat Circa 1854 Burt & Bailey Solar Compass that was almost certainly used to survey Yosemite National Park and San Francisco’s Hatch Hetchy Reservoir. The Canvas bag is AMAZING – stenciled on top of the bag is U.S.D.S. Y.N.P. (United States Deputy Surveyor Yosemite National Park). Can you imagine the pride that Drenzy Jones, the U.S. Deputy Surveyor and owner of the Solar Compass, must have felted when he stenciled that on top of the canvas Read More...

Beautiful 1802 Hurtin Minute Compass

By The Compleat Surveyor

Comments Off

Offered here is a magnificent 1802 Christian Hurtin Minute Compass (#28) – a true work of art. The 1837 painting shows Henry Houston with a Hurtin Minute Compass. It’s probably not the Hurtin Minute Compass I’m offering here, but the compass and the painting are both simply fantastic (the painting is NOT included in my offering). My Hurtin Minute Compass is both Gorgeous and Sophisticated. Hurtin was a master engraver, and his compasses exhibit a unique look that demonstrate Hurtin’s exceptional Read More...

Fascinating Circa 1900 K&E Transit Expertly Modified By U.S. Military

By The Compleat Surveyor

Comments Off

Here is a really interesting instrument. This instrument started its life as a K&E Transit with serial number 3426, and was likely made in the late 1890s. I suspect the U.S. Military purchased this transit when new and transferred the transit to Frankford Arsenal, which was the Military’s R&D center back in the day. Frankford Arsenal swapped out the K&E standards and telescope and installed a Frankford Arsenal Panoramic Sight. The sight used the military’s system of mills (6400 mills Read More...

Wonderful Late 1830’s Ewin Compass With a Chandlee L-T Table

By The Compleat Surveyor

Comments Off

Offered here is a very interesting late 1830s Ewin compass that has seen very little field use. What makes this compass so interesting is the internal chain counter (inside the compass box) and the L – T table on the South arm of the compass mainplate. Goldsmith Chandlee and his successor (George Graves) are the only makers to use internal chain counters and L – T Tables. (An L – T Table converts links from a 25 link 33 Read More...

Colonial Semi-Circumferentor With Engraved Trough Compass

By The Compleat Surveyor

Comments Off

This colonial era unsigned Semi-Circumferentor is one of the more common varieties – trough compass, brass semi-circle, brass alidade and sight vanes, and a wood block. The engraved compass card is another story, however. Wow. Semi-Circumferentors made largely out of wood were supposed to be a fairly cheap way for a surveyor to buy an instrument that could measure independently of the needle. So why would an affordable instrument have such a wonderfully engraved compass card??? I came across Read More...

By M and R Gordon

Comments Off

During the years following World War I, W. Wilbraham Falconer was the Superintendent of Mechanical Treatment at the Red Cross Clinic for the Physical Treatment of Disabled Officers in London.

In his words: ”Arthrometry or joint movement mensuration may be defined as a system for measuring by means of an instrument the various angles of movement of a joint of the Read More...
