That is a beautiful Tula '52.
Since laminate stocks were introduced in 55-56, the original stock on your 52 should be a solid birch stock. The laminate stock on it has never been on another rifle, that is why it has only one set of numbers. It would seem logical that your 52 is a rebuild, because this stock is likely to be a replacement to the original solid birch, as well I can see some markings above the star on the receiver cover, and electropenciled numbers on the gas tube.
About the frankenpinning, IMO, compared to the other method of welding a slim and short pin to the middle of the follower arm, I believe that this method used by westrifle and lever, bell and some others is functionally better. The reason is I have seen magazines that have been pinned on the follower arm, that have bent down and allow the magazine to accept 6 rounds instead of five. Now I am not talking legality here. I am saying that the follower could bend and thus weaken if the owner bends it back a few times.
IMO, for shooters, the westrifle/lever arms/bell method is functionally better because the follower will not bend down even with over-enthusiastic reloading as the force during reloading bears down directly on the pin or dowel welded to the bottom of the magazine. The downside is purely aesthetic since the welding job is indeed amateurish and hastily done. I am sure that if more care and thought were given this frankenpinning process, we would call it by another name. For collectors whose main concern is original cosmetics, then the other method will be better.
It is in excellent condition as described on the westrifle website, I agree 100%, but it is not "mint" as pointed out by tootall in a previous post.
Just keeping it real...a beautiful and exceptional rebuilt 1952 Tula with a virgin laminated stock is what it is.
I'm glad you are happy with it.
