I bought this Lyman 66 aperture sight for a /WinchesterMiroku
1886 I no longer own. It was never mounted. The smaller plastic bag is a target disc, that package has never been opened.
$70.00 + $5.00 shipping, money order or personal check.
Also trade for same sight in same condition for model 1892 Winchester, or Marble's tang sight for one of the Winchester 1994 Centennial (1894-1994) models.
Thanks for looking.
