Yes, if it was said on an internet forum, it MUST be true.
For the record, I do belong to Gunboards and read there. To many Americans, the SKS is like a cooey is here - I doubt many of the GB claimants know much about them, certainly not enough to convince me their one example is a true-blue non-refurb SKS with a laminate stock and that the stock had not been changed out by a prior owner.
The recognized authorities in the US on the SKS are Howie Bearse and Doug Bowser. AFAIK, neither has acknowledged legitimate proof of a non-refurb in laminate wood. Period.
