Ruger has extensive sn data on their website.
If it was manufactured after Dec 31, 1968, the serial number will be plainly marked on the receiver. There will be some numbers under the barrels, but they may serial numbers or just batch/lot numbers that will not help identify the date of manufacture. Serial numbers were not required on long arms in the US until 1969.
