It notes that 1917-1919 there was a substantial of "overlap" between production number and serial numbers. This may not actually be an "overlap" but may indicate that the blades were serial numbered first with the year added when they were completed. For example, there are a few 1906 blades numbered up 82,658 but some 1907 blades numbered as low as 76,848.

Check below in regards to the 1917 data. There is a 54,803 gap between the lowest and the highest numbers when only 400 were reportedly made. The serial number rand 1917-1919 indicates 128,000 blades were made. But the serial number range is 179,607 or 51,607 more blades than reported.

This data says, in part, (from the web page).

Year - No. Made --- Low SN. ---- High SN.

1917 ------- 400 -- 250,327 ---- 305,130**

1918 --- 36,500 -- 304,577 ---- 428,135**

1919 --- 91,100 -- 313,051** - 429,934

** Indicates where serial number are known to overlap the presented (lowest known) serial number of the following year. This was caused when bayonets were dated at the end of the calendar year, then stored for straightening, inspection and stamping with a serial number. At the beginning of the calendar year, when bayonets in production were stamped with the new year’s date and sent to storage, it appears that some of the more recent bayonets were brought out before the slightly older ones.

Low/High serial numbers that differ from observations of Wm. Brophy, as published in "The Springfield 1903 Rifle", are from research in progress by author.
Thank you for that. Also very informative and helpful.
