"On April 15, 1851, the State of South Carolina awarded Benjamin Flag of Millbury, Mass. and William Glaze, owner of the Palmetto Armory, Columbia, a sizable contract for muskets, rifles and pistols. One thousand sabres and one thousand artillery swords were included; "all arms to be made within the confines of the State of South Carolina." Later the contract was amended to delete the artillery swords and adding an additional one thousand cavalry sabres with scabbards. These were made at the Palmetto Armory and were identical to the US, Model-1840. All were stamped on the reverse ricasso "Columbia, S.C. " and some few "Wm. Glaze & Co." on the obverse. Confederate Handguns raises a question as to whether those sabers stamped "Columbia, S.C." are in fact the product of the Palmetto Armory? The answer to this is a definite "yes"" Comparison between those that also include the name of the maker "Wm. Glaze & Co." reveal that the "Columbia, S.C." is struck with the same die on both. An additional question also raised by Confederate Handguns is whether the sabre contract was ever fulfilled? The survival ratio strongly suggests that it was."
