You do not provide sufficient information to identify the rifle.
There is no Sears model 6. The model 6C comes in American and Canadian versions, which are very different.
That depends on the make and model.
Best left to a trained gunsmith.

The Savage Model 6 was Mfg'erd from 1938 to 1968.
It depends on which model. Not all handguns are the same in the way they operate.
Request a manual from S&W or ask a gunsmith for help.
Winchester made the model 1873 rifle and the model 1876 rifle,but did not make a model 1875 rifle.
22 long rifle
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.
Best to let a gunsmith do it.
