Thanks again, all. This is tremendously helpful.

I have attached a couple more pics. The bolt has various markings on it, including on the lugs. These guns sure do have lots of markings. I found what looks like another Izhevsk mark under the rear sight leaf.

Not sure which is the "C" on the barrel?

One thing I'm wondering - if the gun is a refurb, why would the bore look brand spankin' new (and no counterbore)? Would they replace the barrel in one of these refurb jobs?

Thanks!
