Bob, SG's are easy to "fake" by just changing out the stock and floorplate. IMO if it's "fake" it's still worth about $1000 more than if it was a standard grade because the stock and floorplate can just as easily be changed back to original and the SG parts can be sold for about $1000. I have a 250/3000 SG carbine that is impossible to determine if it's an original SG or not but I still don't consider it a cheap gun, I consider it worth about $1000 more than standard carbine.
