A finely crafted unmarked brass bullet mold from the mid-19th century, designed with dual cavities for both round ball and conical projectiles. Likely produced for a .31 caliber percussion revolver, this example reflects typical American manufacture of the 1840s–1860s period. The mold features smoothly contoured handles and integral sprue cutter, operating properly with clean, well-defined cavities. Unmarked examples such as this were often privately purchased or supplied by small regional gunsmiths, rather than factory-issued. Dimensions approx.: 4.625 x 1.25 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. Very good overall, with smooth golden patina and minor tool marks; hinge operates properly, cavities crisp and functional.
