Danny, I have a couple older Savage Model 3's with a bolt very similar to yours, they have a cocking piece that looks larger but otherwise the same. They appear to be made so they cannot be disassembled completely, there are two blind pins in the ones I have and I see no way to remove them.

ADDED- I pulled my rifles out and what I have are B versions, a Savage 3-B and a Stevens 53-B, yours is an earlier version. Mine do have a larger cocking knob which may have been part of the upgrade for the B version, I assume there also was an 'A' version of both? Catalogs never list the alpha character.

One is a special 53-B made for Montgomery Wards. It's marked 'STEVENS' '53-B' on the top of the barrel, 'Wards Westernfield' on the receiver and 'STEVENS Buckhorn Rifle' on the underside of the barrel just in front of the forearm.

Montgomery Ward's had Mossberg scopes made under their own name and this Stevens rifle is drilled & tapped for them.
