Bill: My Berks County research found: Worley/Worly name found both ways on barrels. One Worley, John or Jesse made complete rifles, but I've only identified JW on top of the barrel on only a very few rifles. The Worley family was 4-maybe 5- barrel makers in Mohnton, 7 miles south of Reading on the Wyomissing Creek. Henry the father, about 1830, and sons, Henry Jr., Jesse, John, and possibly the youngest, Theophilus. Most active right before, during, and after the Civil War-primarily percussion era. Twenty plus barrel makers on the Creek, most often seen names on barrels would be W. Pannabacker and Henry Deeds, and later Schnader, (his mill still standing) who supplied thousands to Pittsburgh makers, like Allegheny Gun Works for shipment west. Part of Worley's factory in Mohnton is still standing, used as a warehouse today. This was the town that supplied gun barrels from mid-1700s until the late 1800s - historic markers all over the town.
