 Colt M1911A1 U.S. ARMY Serial Number 
    890199 (parkerized finish) - Shipped March 25, 1943 to the 
    Transportation Officer, Springfield Armory in a shipment of 2,000 guns.  
    One of 106,171 model 1911A1 pistols produced with a duplicate assigned 
    serial number.  It is speculated that the duplication in serial numbers 
    occurred as a result of confusion during the rapid expansion of the ordnance 
    operations in 1941.  At this time, small arms contracts were 
    transferred from Springfield Armory to the Office of Chief of Ordnance (OCO).  
    Springfield failed to notify the OCO of previous serial number assignments.  
    The serial number blocks 801001 - 958100 and 1088726 - 1092896 has been 
    assigned to Colt and were recorded in their production ledgers. 
    At the same time,. the OCO assigned the following serial 
    numbers blocks when they were under the assumption that the high serial 
    number assigned to Colt was 856100. 
      
        | Serial Number Block | Assignment |  
        | 856101 - 856404 | Field Service Depots |  
        | 856405 - 916404 | Ithaca Gun Company |  
        | 916405 - 1041404 | Remington Rand |  
        | 1041405 - 1096404 | Union Switch & Signal |  |
