The total number of gaps is statistically estimated to be 33,487 based on known or observed SN data and purposely distributed proportionately for simplicity purposes each month for all rifles produced from January 1943 to the end of production. These gaps in the SN sequence have resulted in more SNs assigned than rifles made. By definition, a SN gap is either a dropped or unaccounted for SN (вЂњlostвЂќ) or a serially stamped, but defective receiver never used in making a fully assembled rifle, e.g.

SN calculations reflect the reality вЂњgapsвЂќ as well as вЂњduplicatesвЂќ within the serial numbering process. The factory shop-assembly process resulted in final rifle production in no particular SN order or sequence, therefore rifles with higher SNs than the number of rifles produced may exist for any given month.

Also, it is noted that final rifle assembly followed receiver serialization by an approximate average of 2 weeks.

All вЂњend-of-monthвЂќ SNs are calculated approximations only. Serial numbering began with SN 3,000,000 and numerically remained continuous to end of production except as shown below. This report reconciles in finality all rifle inspection approval issues that may have remained after close of each monthly billing period. In absence of actual factory production records predating вЂњfinal inspectionвЂќ via note #1 above, the вЂњfactory invoiceвЂќ record becomes the next most reliable statistical basis for approximating вЂњend-of-monthвЂќ SNs.ДЇinal approved rifle production based on Ordnance Dept., Small Arms Branch, Industrial Division record summary dated March 10, 1944. inspection report data used for monthly invoicing for services rendered under contract.
