Your rifle was made by Savage for Western Auto. It is a Savage Model 46. You can contact Savage for an owners manual. It is a very basic bolt action. Remove the screw on the underside of the forearm to take action out of stock. Push the 2 pins out that hold the trigger group in place, and you can remove the bolt. gunpartscorp was a schematic at their website, under savage 46.

I have a Revelation 2500D and it is very clearly a Savage manufactured rifle. Identical to Savages of same period except for the rollmark.
