Here's some markings I found along the barrel.
Starting from muzzle working back.
(fireball octopus thingy)
A marking that looks out of place, I think it's the number 5
Another marking that's a B
Some weird things that kinda look like stars maybe or a hammer. Hard to tell.
There is an R on the bolt. The R is on it's side facing up when you look at the right rear side of the bolt.
I don't see any other markings at this time.
Two questions: Is it normal for the receiver to have a polish or lacquer kind of look to it? And where can I get an original looking stock? I love the way those look.
