Nice gun, good wood, looks like its mostly original parts including the barrel and the windage knob which you don't see every day. While I can't see the full bolt markings, the only part I saw not HRA is the trigger group, which is IHC (some might find that more desirable).
You could dig into the drawing numbers to be sure, but it looks to me like your rifle is original. That stock is beautiful too.
The markings on the bolt are D28287-12SA B4C. So the bolt and the trigger group are the only non-HRA parts. Overall I'm pretty pleased with it. Worth the 3 month wait!
Gotta get to the range on Saturday to try it out now
