You posted a picture of a stock that’s cracked on both sides there’s no reason to believe that they’re not connected which would make it cracked all the way through. Other posters commented on how they cover up such problems with superglue and then hide the repair.
If I were to purchase a gun that it was cracked in the manner that this one is, and the cracks were hidden with superglue, and it subsequently broke I would not be happy.

Honest repairs are, well,
HONEST

Out there doing it best I can.
