I chose instead to employ the vernier tang sight, and for me, this is the jewel of the No.2's sighting system. |
The vernier callipers I guess would do a very fine measurement, down to a millimetre or perhaps less. |
To measure the axial deformation, Bishop and Henkel used a vernier telescope, which was focused on top of the steel ball. |
Models range from match-grade vernier tang and windgauge front sights, to open, sporting tang, and globe front sights for hunting. |
The presence of the ladder sight complicates the use of the vernier, especially at close ranges. |
He designed a simple device similar to that of the modern vernier for increase in the accuracy of measuring lengths. |
