Original six-count packet of seamless skin cartridges manufactured by D.C. Sage of Middletown, Connecticut, for the .36 caliber Whitney Navy Pistol. The label reads “Hotchkiss’ Patent, Feb. 11th, 1862,” referring to the patent covering the use of animal membrane “skin” cases that were more durable and moisture resistant than combustible paper types. These cartridges represent a significant wartime development in percussion ammunition technology and were widely issued to Union forces during the Civil War. Dimensions approx.: 1.5 x 1.625 x 0.5 in. Provenance: The Al and Carol Cali Collection. Pickup & Shipping: This lot may be picked up free of charge in Gardnerville, NV. It can also be delivered to the Annex Auctions facility for pick up in Sacramento for $25 pre invoice. Shipping via FedEx within the continental U.S. for $50 + 1.5% insurance (unless waived in writing). Combined lot shipping available. Good. Wrapper shows moderate wear, staining, edge separation at corners, and scattered losses primarily along the upper edge, but the label remains largely legible and the packet structurally sound.
