GREAT rifle and easy to break down for cleaning, Best thing to do is unload it first then look at the owners manual as it gives a complete part break down
DON'T!!! unless you absolutely have to. you can cause damage if you don't know what you are doing. and parts are hard to find.
All Winchester model 12's are take-down designs. Winchester made a model 25 which is solid frame and very similar to the model 12.
don't take down a Winchester model 52, the way they bedded the rifle was a mystery. It may never shoot the same if you take it apart.
