I saw this rifle on GB earlier this month, my thoughts were that the stock was replaced and it probably wasn't original, but hard to say with the sellers pictures, - you show some of them but there were more.
As BiO and Craig stated the stock should be serialed externally and have acceptance in several locations, this is typical throughout this year, so it isn't a failed rifle held back as is the case with SDP in many cases (which accounts for the varied patterns imo). He does show the buttplate, which is matching and original to the rifle, but he doesn't show the wrist and lower buttstock, but I assume that is because nothing good is there?
Also typically when the trigger guard stands out like this there is a problem with a rifle (looks screwed in all the way but no direct pictures of the TG group), and he doesn't show a heads on view of the receiver, looks like the gap (fit) isn't all it could be in some of the pictures. Naturally these observations were based upon the few pictures and any of them could be wrong as the angles are not the best for an evaluation of this kind. Personally I think $1700 is too much unless the stock is original, serialing along the lower buttstock, and or internally might lead to clues, acceptance on the wrist area or lower might be a positive, but short of these things, I think you are really gambling at $1700... though it is a good-date to find when matching-original, $1700 would be a good price for one, but I doubt this is a right rifle. (more information could legitimize the rifle, but what is shown is not right.)
