Deluxe Large Siler Flintlock. Plate measures 5 1/4" long by 1" tall. Jim Chambers has made several improvements to the classic large Siler which include a taller cock to use more of the frizzen face, the half cock notch is changed to allow for the use of a 3/4" X 7/8" and still clear the frizzen, and the toe of the frizzen is changed to allow it to cam over sooner. This combination works faster, gives better spark and extends flint life. Uses 3/4" flint, #FLINT6F.
