What are these markings on my cannon?

[41 Colt]

It looks like it may be related to pressure. It's Spanish made by Dikar and is .69cal with a steel barrel.

According to an old copy of Small Arms of the World the shield with an X and crown is the mark of Eibar Proving House located in Spain.

Three balls = Definitive BP proof for smooth-bore barrels and breeches.

Helmet over shield with X = arms of the Eibar proof house, Basque Region of Spain, famed as a centre of firearms production since around 1550.
