Krag rifles at 1907 Camp Perry National Matches note militia uniforms Pope sight micrometer, attached to the rear sight elevation leaf up front
Of interest in this photo from Perry in 1907 is the use by the shooter in the foreground of a Pope sight micrometer, attached to the rear sight elevation leaf. Harry Pope’s micrometers, unlike most of the several varieties that were made and sold, were intended to be left in place while the rifle was being fired. Photo via American Rifleman
