What do many gunsmiths prefer not to remove when restoring guns with a split buttstock?

Many gunsmiths prefer not to remove the original wood when restoring guns with a split buttstock due to the historical and aesthetic value it holds. The integrity of the original material is significant not only from a craftsmanship perspective but also in maintaining the authenticity of the firearm. Original wood can contribute to the overall character, feel, and balance of the gun.

Preserving the original wood often allows for repairs to be made that maintain the original style and construction features of the firearm. This is particularly important in the collector's market, where maintaining originality can significantly influence the value of the gun. Repairing the split rather than replacing the original wood ensures that the history of the firearm remains intact, which is highly valued by enthusiasts and collectors alike.
