Hi John,
I went through all of my Civil War Arms books dealing with the Starr Manufacturing Company.
Perhaps the original Starr-Percussion contract with the Federal Government required the eventual delivery of "up to and including" 30,000 Starr-Percussion models, and the "30,000 number was so stated in the original contact.
However, with the success of the Spencer rimfire cartridge
the Federal government (perhaps)revoked the original contract with Starr, and requested manufacture of the newer cartridge model that would chamber the Spencer 56-52 metallic rimfire cartridge, and the Starr manufacturing plant began production of the NEW cartridge models with the next sequence of available serial #s i.e., in the 30,000 range. Maybe
The rimfire cartridge model was successfuly tested in January 1865, and between March 28, 1865 and and April 11, 1865, 5,002 Starr rimfire cartridge models were manufactured, however, not many of these models were actually used in the Civil War, as they were produced too late; the earlier percussion-Starrs were delivered and issued in greater numbers to units during the Civil War.
