Lafayette Mills worked in Jo Daviess County, Illinois, right up against the Wisconsin State Line. He worked both alone, and with a partner, James Thompson. I have a Mills & Thompson rifle, stamped "L. MILLS & J. THOMPSON", on the top barrel flat, and the underside of the trigger guard, with two separate one-piece stamps. The buttplate, trigger guard, and set triggers, are all hand-forged iron, and it is stocked in ash.
