In perusing Pierre van der Walt's book I noted a highlighted passage. He says John Rigby brought out the .45-2.4"-Match cartridge in 1870. Done on a shortened .45 BPE 3-1/4", might have been with coiled brass case ? Something to look into ... Who did the .45-90-2.4" with drawn brass case first ? John Rigby or Sharps ?
