The Gallager carbine was designed by Dr. Mahlon J. Gallager, a Southerner by birth, and manufactured under license by Richardson & Overman in Philadelphia where Gallager had a dental practice. Under 18,000 Gallager carbines were manufactured in three variations. The first two versions were widely used during the Civil War by the Union cavalry. This example is a standard cartridge model and was manufactured during the Civil War. It has a blade front sight, notch and folding leaf rear sight, "GALLAGER'S PATENT/JULY 17TH 1860" and "MANUFACTD BY/RICHARDSON & OVERMAN/PHILADA" on the lock plate, matching serial numbers, and a smooth stock with blued patch box, saddle ring bar, and ring. The top of the barrel behind the rear sight is stamped with "J.M.D." The left side of the stock just behind the sling bar has a "WHB" cartouche, and matching initials stamped on the comb.
