Leader was a trade name used by C.S. Shattuck, Hatfield, Mass (1880-1890), Hopkins & Allen, Norwich, CT (1868-1915), and Harrington & Richardson, Worcester, Mass (1874-c.1980). Are you sure it is a 28 caliber? This was a common size for percussion guns, but I cannot find any percussion revolvers by any of these manufacturers. I also find no references to any .28 cartridges.
You unlock the revolver after achieving level 28.
