The Batavia guns were the low priced or "field grade" models of the Baker Gun & Forging Co. To reduce costs the Batavia line did not have the "firing pin block safety" or the "draw block" which passes transversely through the barrel lug and mates into recesses in the frame, of the graded Baker hammerless guns and the Model 1897 hammer gun. After WW-I with the rise of repeaters Baker sold their gun business to H&D Folsom Co. a major marketer, manufacturer and importer of low priced guns. Folsom added the 20-gauge to the Baker line that they produced. Folsom-made Baker guns normally have an F before or after the serial number. In the very last Baker ads that I've found in old sporting magazines from April and May 1928, and October 1929, Folsom also offered a 410-bore Batavia Leader, though I've never seen one.
During the Baker Gun & Forging Co. days there were several variations of the lower priced "Batavia" line. From a 1909 copy of The Baker Gunner -- The Batavia Leader had twist barrels and listed at $25 -- The Batavia Special had steel barrels and listed at $21.75 -- The Batavia Damascus had Damascus barrels and listed at $28 -- and, finally the Batavia Brush had 26-inch twist barrels and a straight-grip stock listing at $24 and offered swivels and a sling as an option for $3. There was also a Batavia Ejector that listed at $35 with steel barrels and $37.50 with Damascus barrels. By the H & D Folsom days they were all consolidated as the Batavia Leader with steel barrels.
