Savage 420 - disassembly ?

[Sudsy]

I recently picked one up in very nice condition, unfortunately the action doesn't seem to have been cleaned since it was made 80 years ago.
No problem with everything I can get to, removing the wood is relatively simple - it's getting inside the receiver, which is pretty gummed up, that I'm not sure about.

I searched for videos with no luck.

I ran some naphtha through it and reoiled.
Smooth as butter

Would still like to know if there is an order of operation for disassembly for future reference

Numrich has an illustrated break down on their site, finding a manual may be near impossible.

It's the order of operations I'm trying to figure out
