B-247 SURVEYOR'S COMPASS. Benjamin Pike & Sons. Unusually small compass probably intended for use by farmers rather than professional surveyors. There's a similar Pike instrument in the Smithsonian collection. 4" steel needle with lifting arm, single level vial on south arm, no dial cover. In original mahogany box with sighting vanes and Jacobs staff mount. There's a second mount that may not go with it but it's in the box so you get it.Fine 400-800 NOTE: Absentee bidding ends 5:00pm EST on Friday, March 29, 2019.
