The Wesson Rifle shown is not the Wesson Civil War Carbine! The Civil War era Wesson Carbine is chambered for the .44 Wesson cartridge; it will have 2 sling swivels, one on the bottom of the barrel and one on the lower end of the trigger guard; the butt plate is a military type much resembling a Maynard Carbine butt plate; the slotted link will be on the right side of the frame; and there is no extractor. You may see some examples with a counter-stamp on the top barrel flat which reads: "Kittredge & Co./Cincinnati O.", these are guaranteed Civil War used arms. Kittredge & Co. sold thousands of Wesson Carbines to Militia units in the mid-west area who couldn't procure arms any other way. The majority going to Kentucky and Illinois, with lesser numbers to Kansas, Missouri, and Ohio. Because the Wesson fired a rim-fire cartridge very similar to a Henry round it was quite popular in its time, although the Federal government did not purchase many of them. As always, politics played a big part in what the government did, and did not do. The Wesson company survived the end of the ACW and continued to be a viable business until 1888. The small Wesson Carbine developed into a very highly respected target rifle and won numerous matches in its day. There were some 8,000 Wesson Carbines produced by the end of the ACW, and it had been a relatively inexpensive Civil War Carbine to collect until a recent flurry of interest a few years ago caused the prices to more than double.
