Overall length 40" (artillery) or 37" (cavalry); barrel lengths 24" (artillery) or 21" to 21.5" (cavalry); caliber .58. Markings: same as on Athens production rifles. Artillery and cavalry carbines were manufactured in the same serial range as the Athens production rifles (about 2000 through 7650). As in New Orleans production, the artillery and cavalry carbines are distinguished from one another by their respective lengths. Unlike New Orleans/Selma production, however, some of the cavalry carbines are mounted with sling swivels of the artillery style, while others bear the sling ring on the left side and additionally have a swivel ring to secure the ramrod.
