I read somewhere that when the 03A1 was approved SA still had thousands of Finger groove stocks and the continued to use them until they were gone and because except for DCM sales vary few rifles were being built for the Army there for few if any 03A1s. So without DCM or National match documentation. So should one consider a 1903 in the correct serial number range with the C stock as a original issued 03A1 and pay a premium for it
