Manufactured date?

I just received a Savage 110, left hand, originally 30.06 but was rebarreled to 22-250. Checkered wood stock, hinged floorplate. The serial number on the receiver is C019343. When was it manufactured? I was told it was BR model but the receiver does not have no other marking other than serial number. Please help

According to the serial#, 1977. The part that confuses me is the hinged floorplate. Savage first used a hinged floorplate in 1962, and found it opened upon firing, so they discontinued it and used a stamped magazine cover the through hole. It is possible this was actually made earlier and was in storage for a long time. The serial number is the last thing assigned before it leaves the factory.

I get a manufacture date of 1975.
