The firm was in operation as a weapons manufacturer from 1861 until the Federal capture of Nashville in 1862. During that brief period of time, the firm manufactured a large number of swords for the Confederacy ranging from enlisted men's sabres to staff and field officer's swords.
The sabres produced by Nashville Plow Works tend to be on the crude side and are often associated with the western Confederate armies.
One if the most desirable swords of this firm is the cavalry officer's model which bears CSA on the underside of the guard as depicted below.
Note the dimpled design in the brass guard which is another hallmark of the firm.
Please note that these swords, especially the officer' cavalry sword, have been mass reproduced. Due to their popularity, originals command significant prices. Buyers should beware of fakes as a mistake will be costly.
The sword shown immediately above is a reproduction that is commonly found on the market. It is produced for reenactors and collectors of reproductions and can be obtained from a variety of sources on the Internet. The price tag for the reproduction is dwarfed by that of the original.
