B66-250 CALCULATING PROTRACTOR. G.H. Whitescarver. Brass, 10-1/2" long, with rotating head that can be locked at different angles. Marked "G.H. Whitescarver's Calculating Protractor." Mr. Whitescarver was a resident of Richmond who apparently attempted to patent his instrument in 1859; after the Civil War broke out he obtained patents for this thing and another unspecified surveying instrument from the Confederacy and made a living teaching engineering and surveying. He may also have served in the Confederate Army. Brass is oxidized but undamaged. From the collection of Chuck Morgan. Good+ 150-300
