I know CIP is transnational and consistent now, but in the day of that Astra, most countries had their own proof law and test standards. Belgium set a lot of the early standards, German proof law was modeled on the Belgian with local "refinements" like marking rifle barrels with the gauge value. Spain was a latecomer, they didn't have regularized proof for years after.
It amazed me how late a first proof with black powder hung on.
