I can tell you that receiver is 100%, without a doubt, scrubbed. It's plain as day.
The 5 digit serial on the receiver does not surprise me. As a matter of fact, the gun I used for my SKavor project, was also a scrubbed 5 digit gun.
What does baffle me, is the rest of the serialed parts. The V is odd enough, but the 5 number digits are also odd. They are made up of different fonts. The "v" the "1" and the "7", are early chinese font...like you'd expect on that year of SKS. The "22" is a different font. But they look like they were all stamped at the same time. And there is no signs of scrubbing on the magazine, receiver cover, or trigger group. The bolt carrier is definitely scrubbed, and also has completely different font from the rest of the gun.
