What is the shank threading on aperture sights for Lyman, Redfield, Williams and Brownells made aperture peep sights? I know Marbles is different. Am interested in the Lyman types only.

Most Lyman and Redfield used a 7/32-40 thread aperture. Kind of a non-standard thread.
Thanks -
7/32-40 is #12-40 Taps are not common but available
