Finally one of you

Ok ok. Im new. Like I got my license in the mail yesterday new.

I know almost nothing. Although I already know that those who know don't like this gun. Ok. But it's my first piece, and I got it for free from a friend by helping them out, and it hasn't seen a single shot fired yet. Brand new. I cut the tag off today.

...it's a Federation SPM-12

I've got questions. Go easy on me.

1) I leaned in my gun safety course that I match the head stamp with the data stamp. But wtf, I can't find the data stamp. Unless the info is buried within the serial

number I don't know what ..inch (?) of the shell is. And I feel like it's not cool to share the serial number? Online searches assume 3" but I need to be sure.

2) Even though I got this second hand, why can I find a manual online??

3) What the heck is this switch for in the second picture?

4) I assume these are my chokes in the third picture. I don't really know how to differentiate them. Whatever comes stock has this, I assume flash suppressor (see pic 4), seemingly welded to the stock choke. How do I know which choke is which and transfer the flash suppressor?

Holy hell the amount of dudes commenting about the takedown lever that have zero clue what they're talking about is peak cringe. Why would it be "decorative" or a magazine release when its so high at the top of the magwell? Those guys have clearly never handled a gun with a detachable mag or cleaned a turkish shotgun. If you dont know what it is just zip it, no need for fudd information yah goofs. 

You have to pull back on the pump and switch it down to unlock your bolt assembly from the receiver and then when putting back together you pull back and switch it up to lock it up. I recommend taking apart every gun you get before taking it to the range and cleaning it and understanding how it functions. It'll be easier to tell if its becoming damaged over time like this.
