M1 Garand Stock Fake/Refinished?

[BVZ24]

I'm relatively new to the collecting and differences of the M1 Garand. Picked up this stock as part of a lot with the intent that it would look nicer on my SA 8xxxxx than the stock I have until I can find the correct one at a good price. When assembled, it seems very undersized compared to the other stocks I have. The shelf at the heel does not fully extend past the heel like the other stocks, and the trigger side of the magazine is flat instead of curving back up to the floorplate. This stock is also significantly lighter in weight. The butt is also undersized to the butt plate.
This stock has the DoD marking in the usual spot and the edges feel relatively sharp, with finish loss on some of them.
I know some stamps can be faked, and I'm suspecting this stock might have been heavily refinished and stamped. The finish doesn't really have any of that linseed shell that I'm used to seeing on old arms, and feels like there might be some ripples from uneven sanding. Typically when I feel ripples, the corners are usually very round however.
I'm not too broken up, because I wanted the lot and not the stock. Is this a correct condition for a stock to be in?
