Some years back there was a very high condtion Folsom Batavia Leader 20-gauge kicking around the gun shows in the mid-Atlantic area, and the dealer seemed very firm on $1100. For a collector it did have a lot of condition, but as a using 20-gauge it was very heavy at a shade over seven pounds. My Black Beauty Special Ejector 16-gauge with 30-inch barrels weighs in at 6 pounds 12.1 ounces.
In the late 1920s some of the Folsom magazine ads list a Batavia Leader .410-bore, but to the best of my knowledge, no one has come up with one. For some reason, it seems the case colors on these Folsom era Batavia Leaders seems to stand up quite well.
