Smith is probably a good possibility. John McAulay, in Carbines of the Civil War 1861-1865 mentions an 1860 small arms test, where one Smith fired 1000 times without apparent weakening of the spring. One of their comments was '"This gun, from its simplicity of consturction, apparent strength of parts, the ease with which it is loaded and the general accuracy of firing recommends itself strongly, and is particularly adopted to the mounted service. In view of these considerations the board entertains a more favorable opinion of this arm than of any other breech-loading arm presented, and therefore recommends it to be adopted to a limited extent, for a further test, in active service on a campaign."
