    Specific SN# and years of modifications from Springfield.

    Serialization Date Chart
    Last Update - 04/06/2005

    Springfield Armory was on a Jul 1 - Jun 30 fiscal year and reported numbers of rifles completed for each year but not
    the dates of serial numbers struck. From 1907 the Armory reported the first serial number of the year. Since no effort
    was made to use the receivers in numerical order, considerable variance exists between the number of rifles built and
    the number of serial numbers struck. Therefore, rifle completion dates can not be precisely determined.
