Yeah sorry to say nothing on the rifle is correct. I run into two types of rifles like this. Ones that were put together as match rifles back in the day with a scope mounted. Otherwise they are not meant to deceive as a Marine Sniper. They were just a scoped rifle put together back in the day when sporters were popular and today people confuse these rifles as being a Marine rifle. This one on the other hand is not like that. It was meant to deceive or someone was trying to copy a Marine Sniper. They just didn't do good job on copying one. The scope on the other hand is real. In the states that would probably be close to a 4k scope.
Some of his info he posts on the history of them is also not correct.
Really you don't need paperwork at all to confirm one. All known rifles are nearly identical. They are so distinct that even with a few pics it's pretty easy to tell if they are real or not. The only time it gets complicated somewhat is if they have been sporterized or I run into ones that guys have messed with to make them more correct to what a book states. The only problem being the books were wrong on some of the info and collectors have incorporated the fake traits from books onto real rifles. If you even tell me the serial number and barrel date, I have a pretty good idea if it's real or not before I look at it
The team docs Tim Plowman found at the archives helped so much in decoding the info on the real rifles.
