Savage Model 110 DL series H 30-06 age?

[Crummyrummy]

Hello. My grandfather passed away last year, and recently came to possess his guns. One of these guns is a Savage Model 110 DL 30-06 with a serial number beginning A633###.
I have been looking but I cannot find a time frame that correlates with a serial number starting with A.
