Production Hiccup - As per J.C. Harrison's book, "A collectors field guide to U.S. Military Arms: Volume Four" , it is stated: "SN's 128,617 through 129,616 falls within the Springfield Armory's assigned serial number range. But, these pistols have Colt markings and pistols noted in Colt's factory ledger as having been inspected by Colt between May 6, 1916 and June 30, 1916. These pistols do not have Colt assembler marks or Final Inspection Stamps. They do however have the Colt "H" provisional marks on the frames and slides and some have the "G" (Government Contract) Colt' marking at the frames disconnector hole. Additional Colt pistols through about S/N 133,000 appear identical to the earlier pistols, but are not mentioned in Colt's ledger. None of the above pistols are listed in Colt's shipping records or U.S. Ordnance Procurement records. So what happened? It is of the 'authors' opinion that these pistols were assembled by Colt, using excess receivers and component parts received from Springfield Armory. In order to devote more machinery and personal to production of the M1903 rifle; Springfield terminated their production of complete M1911 pistols on April 15, 1917 at S/N 127,978. The reason for Colt producing pistols within the Springfield assigned serial number block before Springfield actually suspended production is unknown, and only adds to the mystery surround these pistols. These Colt pistols between S/N 128,617 to 133,186 do not exhibit the workmanship of other documented Colt models within the same time frame. Hand fitting of slides and component parts is apparent on these pistols. If these pistols were in fact assembled using government parts, the final acceptance stamps not have been required because the pistols were already U.S. Government Property.
