Secret Service.
An extremely rare decoding device used by the Confederates to encrypt secret messages throughout the Civil War, created by gold and silver worker, Francis LaBarre, ca 1862. At the start of the war, LaBarre (b. 1818), who was working in Washington, DC, fled the city for Richmond, where he was contracted by the Confederate Army to produce brass cipher devices as well as other medals. LaBarre enlisted in the Confederate Army as a private on April 22, 1861, in Alexandria, VA, and was mustered into Co. H of the 7th Virginia Infantry. Within a year, he was discharged on May 14, 1862, but during his time in the army, LaBarre’s official military occupation was listed as “plater.” He is referenced as a “tinner” in an 1864 Baltimore City Directory as well as an 1870 Baltimore census.
