Thanks for the info.  No Hatcher hole on the left side.  The rifle is owned by the son of a former CMP employee who bought it in the 80s.  He did say the wood was replaced with a C stock but other than that it's just as the CMP received it.  The Parkerizing looks recent and the barrel and receiver match.  The rear sight looks great, the barrel bore and crown look perfect.  Just not much wear evident overall.  It's a very odd combination.  It was cheap so it's mine now.
