I recently acquired this CMPicon Springfield that has a serial number indicating it was produced in March, 1945:


The date stamping on the barrel, 1 S A 2 45, would indicate it was made in Feburary, 1945, and is probably original to the receiver:



Bolt


Other marked parts found upon field stripping the rifle are also SA stamped:

Operating Rod



Trigger Group


The receiver leg has an electro-pencil mark LEAD over 1.65 indicating that the rifle underwent a rebuild at Letterkenny Army Depot in 1965:


The stock has the circled P proof stamp behind the trigger guard and a very faint partial cartouche with SA over an O on the left side of the buttstock:


I found a discussion on another forum that suggested M-1s with the electro-penciled Army Depot rebuild dates may have come directly to CMP from the former DCM inventory of overhauled rifles.

I would deeply appreciate any questions, corrections or additions to the information I have regarding the history of this firearm based on the data I have gathered so far.
