SRS check and information

Hello Milsurp friends,

Could I please get an SRS check on M1903 rifle serial number 1476131 with SA barrel 3-33. it is interesting that the "7" "1" & "1" of the serial number are struck much deeper and bolder than the rest of the numbers.

Question.....The serial seems to be later 1934 production....could a 3 -33 barrel be original to the receiver? There is an RAP stamp on the left side.

Am waiting response from seller on questions.

Thanks,
