Well, it's up to you whether you want to knock out the S/N or not. Most of us post it. I like to see the S/N of the receiver and then all the correlating matching parts with that s/n. That would include a closer pic of the left side of the butt stock, back of receiver cover, trigger group, orig. 10rd box magazine and bolt. We also like seeing other marks if the carbine I'd suspected to be an original, non-refurbished sks. Since yours is a refurb (and that's not a bad thing, mind you), the other shots aren't going to show us anything as the marks won't be there. Non-refurbs still have some original marks that weren't sanded off during the refurb process since they were never refurbed.
You've got a great shooter, that will only grow in value, especially at the price you paid.
