Developed shortly before the outbreak of World War One, the Chauchat (also labeled the "CSRG" for Chauchat, Sutter, Ribeyrolles and Gladiator) was the primary French light machine gun on the Western Front, while also actively used by the American Expeditionary Force until the 1918 BAR came online. A number are known to have been transferred from France to Finland, where they saw use during the Continuation War. Blade front and tangent rear sights, both offset to the left, with the left sideplate marked "SIDARME/C.S.R.G. 23328" ahead of the Finnish "SA" inspection mark, with a three-position "S/M/C" selector switch, hinged bipod, dual pistol grips and a hardwood buttstock. The chamber has been plugged and welded, but the bolt is free of visible welds or alterations. Magazine not included.

Fair. Scattered rust on much of the surface, brown patina overall, and some handling marks, with areas of original blue remaining. Wood shows minor scuffs and dings. Mechanism is stiff, but appears to be in good order.
