With the letter F in the serial number, your Batavia Leader was made after Baker Gun & Forging Co. sold out the gun part of their business to H & D Folsom Arms Co. of New York City in 1919. The Baker/Batavia guns put out by H & D Folsom Arms Co. 1919 to 1929 were assembled at their factory in Norwich, Conn., aka Crescent Fire Arms Co.
