Lock Assembly

15 parts

  • Fly

    Prevents the sear catching the half-cock notch during firing.

  • Frizzen

    The steel struck by the flint. Called the battery, or confusingly the hammer, in British usage.

  • Frizzen Spring

    Returns the frizzen over the pan and holds it closed.

  • Jaw Screw

    Tightens the top jaw onto the flint.

  • Lockplate

    Base plate mounting all lock components.

  • Mainspring

    Drives the cock forward.

  • Pan

    Holds the priming powder.

  • Pan Bridle

  • Sear

    Catches the tumbler notches at half and full cock.

  • Sear Spring

    Tensions the sear against the tumbler.

  • Top Jaw

    Clamps the flint against the cock.

  • Tumbler

    Rotates with the cock and engages the sear.

  • Vent Liner

    The channel from pan to main charge.
