Developed between the World Wars, the Model 1924 was intended to replace the WWI-vintage 1915 Chatellerault. While a fine weapon on paper, the 1915 was notably less than fine on a trench line, suffering chronic reliability problems. Starting over from scratch, the French took inspiration from other machine guns of the day, like the Lewis Gun, Hotchkiss, and the Browning BAR. Overall a solid weapon, it successfully addressed the issues with the Model 1915. The 1924 was updated in 1929, due to an ammo issue; the original 7.5x57 French cartridge was long enough that an 8mm Mauser could be shoved in it's chamber, which created a hazardous situation for both weapon and shooter, and as many German-made machine guns were in French arsenals this presented a danger, calling for the creation of a new, shorter 7.5x54mm French service round. Blade front and tangent peep rear sights, with a hinged folding dust cover for the magazine well and ejector port, and a swiveling bipod. The trigger housing has two triggers, one for semi-automatic fire and one for full auto. Fitted with a grooved and ventilated forearm, smooth pistol grip, and a straight buttstock with a flip-up buttplate that covers a small compartment with a spare receiver pin. Included with the gun are two extra magazines, a canvas magazine pouch, smaller canvas tool pouch with small tools and clip guide, and an extra barrel. Included paperwork indicates it was overhauled at the Ohio Ordnance Works in 2016.
