I have a 300 savage serial no. 741346 and on left side is 300 savage and looks like SP after savage. I don't see any reference to SP in any remarks about the Savage. I purchased the gun in homestead, pa. In 1955. Does the SP have any significance. Can the serial no. Give a date it was manufactured.

You did not supply all needed information so I am just guessing this might help.
