Thanks for all the contributions, the google image search didn't turn up much. The nitroexpress posts were great, they really were.
But, I was really looking for a good pictures of original Parker-Hale cocking piece for a Mauser cocking piece. The one on the Mauser in the nitroexpress thread is a modification of another Parker-Hale sight. What I was really hoping for, would be pictures like Mike Harrel posted, one's that show things clearly enough
that I could, knowing the diameter of the cocking piece, make measurements from. I promise that I will be a good citizen of this board and make available a detailed procedure for making a base.
