The cannon was a result of the Royal Ordonnance of October 7, 1732, enacted to reorganize and standardize the King's artillery.

Whereas numerous formats and designs had been in place in the French army, de Vallière standardized the French sizes in artillery pieces, by only allowing the production of 24, 12, 8 and 4 pound guns, mortars of 12 and 8 French inches, and stone-throwing mortars of 15 French inches. The 24-pdr was the largest caliber available to French artillery in this system.

The cannon used core drilling of the bore of cannons founded in one piece of bronze, a method developed by Jean Maritz, which allowed for much higher precision of the bore shape and surface, and therefore higher shooting efficiency.

As with other de Vallière guns, the 12-pdr was also highly decorated and contained numerous designs and inscriptions.
