This three digit serial number (626) Gallager carbine that was manufactured by Richardson & Overman of Philadelphia with a total production of about 15,700 in the 50 caliber. This is a single shot, breech loading percussion carbine with a walnut straight grip stock and a patch box. The lock has the early marking "GALLAGER'S / PATENT JULY 17TH 1860" over the serial number just behind the hammer. The front sight a fixed pinched blasé and the rear a folding leaf style. There is a saddle ring bar and ring mounted on the left stock wrist. The Gallager saw extensive service during the Civil War including cavalry regiments from Ohio, Tennessee and West Virginia.

Fair. The metal parts show signs of cleaning at one time or another, the barrel and buttplate are bright and there is overall scattered minor pitting. The stock is good with a small crack on the right side at the buttplate tang and there are a number of minor dents and nicks overall. The heavily worn stock remains fair. The lock marking is partially obscured by pitting. Mechanically fine.
