I am looking to mount a tang sight on a late model Marlin 93 made 1924 in 32-40. The tang is drilled and tapped with two small, same size filler screws about 1.10 inches center to center. I noticed Marbles makes a new tang sight for Marlin 1894 and 1893 but they do not give the dimensions of the hole spacing. Anybody ever mount a tang sight on a Marlin 93?
