Also, it's worth noting there has been much discussion about this on SKS boards. The following quote sums it all up nicely.

There are a lot of assumptions flying around about the Russian SKS, agreed. I have heard this one, too. And I think the basis for the myth is the 'r' stamp following the year on all receiver covers and original stocks. Blinding idiots (blidiots) think this is an arsenal "r"efurb stamp, not realizing that Russians use the Cyrillic alphabet, not the English.
The Cyrillic 'r' is the first letter in the Russian word pronounced about like "goda" - meaning "in the year of". It is not unlike a copyright mark or 'circa' term for us. It has of course nothing at all to do with the refurb process.
I also have unwrapped a mint '55 Fazakerly from the mummy wrap and cosmoline and understand what un-issued milsurp means. No such thing happened here in the U.S. with Russian SKS's. The very best of them were gently worn, all original, non refurbs. I call these 'as-issued'. And of course the refubed ones seemed more nearly new than these. But there were no perfect, unblemished, cosmolined wrapped for storage and unissued examples. Maybe you'll find them in Canada. Don't know.

If you like, here are some common terms I'm trying to better define regarding Russian SKS's. Your input would be appreciated:
un-issued/non-issued : meaningless to me. I've never heard them used in reference to the milsurp Russian SKS. Don't believe anyone's seen one. Commonly misapplied to minty refurbs.
as-issued : the collector's prize. A rifle exactly the way it came off the production line at Tula or Izhevsk. All the serials match. All the parts are original. No refurbishment marking. Complete and nothing missing. These usually show some gentle wear; they appear their age and have not been refurbished. You know, it's the refurbs that appear to be 'like new' rifles.
non-refurb : implies it is 'as-issued' but without the full commitment. There are no refurb marks, no obvious replacement parts, no refurb black paint, and the serials all match. But the rifle may not be complete, and in fact a previous owner might have turned a non-refurb into a bubba with plastic bits and high-cap magazine. It might not have been sent in for refurb in the USSR, but who knows what you're holding.
refurb/re-arsenalled : has been back to the factory or one of the SKS refurb facilities before import to the U.S. It might have a refurb stamp (or it might not), parts were replaced and therefore serials might not match, paint might have been applied to some metal, the stock is almost certainly a replacement. These are very easy to spot and differentiate from as-issued Russian SKS's.
all-original : not the best way to describe an SKS. I am dubious when I hear this because replacement stocks on refurbs are often renumbered to match the rifle and this confuses amateur sellers/buyers as to its originality. Ideally, the term means there are no apparent replacement parts which implies a non-refurb status, and may even be in as-issued condition.
unfired/new-in-box : these are important terms that usually refer to mint status on collectible firearms and are totally misapplied to imported milsurp weapons where no such proof can be offered. Here, these indicate only that after importation (and re-packaging) the rifles have never been shot. These terms might be equally mis-applied to 'as-issued' or 'refurb' Russians. And while a refurb actually does look brand spanking new out of the box (because the refurb process brought them up to excellent mechanical condition and like-new appearance), this term should be reserved for production new firearms. It simply does not mean the one you buy hasn't seen great use and abuse and then been refurbished, imported, and repackaged.
