Give us a better photo of the left side of the barrel shank. Straight on.
Like this:

Also, the base (remove the scope mount). Base is under the scope mount.

From what I see, It is very questionable.
Scope looks real. Not aftermarket.
Scope mount is aftermarket and not original.
Stock color and finish is wrong.
There are no scope numbers on the left side of the barrel shank. There should be or evidence of it being removed or altered.
The "proof marks on the barrel shank should be on the top of the shank on a sniper. this allows for the marking of the scope numbers on the left side. There are no "proof marks" on the top running over to the right side on this rifle.
The import marks run "under" the scope mount. That shouldn't be.
The "dot matrix" import marks were used by CIA in the later years. Not the early years. So, I don't think this is a Century early sniper rifle (which were just re-snipers anyway and not real). The dor matrix import marks came well after they were making "re-snipers".
This appears (without further photos I requested) is a "re-sniper" rifle and not original. Although, if I could see the left side of the barrel shank, I could confirm this or MAYBE reverse my opinion.
Is that the original color of the stock, or have you "played with" the photos a bit?
But only a "sniper expert" can say for sure. we have a couple here on the forums.
