FINE PRE CIVIL WAR 1858 WATERVLIET ARSENAL BRASS ARTILLERY CALIPERS

From America's oldest arsenal. Deep, clear stamp reads 'U.S. WATERVLIET ARSENAL 1858' with a bold, stunning eagle logo above. Dovetailed steel-tipped heavy brass construction. Uncleaned as found. 

Artillery or Gunner's calipers were used to measure the diameter of artillery shells. Only a handful of these have made their way to auction in the last few decades with even fewer dated as these are. A rare opportunity. Top shelf. Insured shipping.
