Volume 31 of Shooting and Fishing (Oct 1901-Oct 1902) tells a lot about a revival of long-range shooting after the losses by American teams shooting the Krag to Irish and Canadian teams.  Farrow retired his Krag and bought a Winchester High Wall Musket, in .30-40 Krag, fitted with a No.3 round barrel.  The rifle came with a 1901 Krag rear sight and standard military front sight.  Farrow added a vernier tang sight, another tang sight mount on the heel of the buttstock, and a windage-adjustable globe front sight with spirit level and interchangeable inserts.
