On the Belgian Express Rifled Barrel theme, Belgian Express Rifled Barrels underwent proof per the German tables of the period. Sources give that there wasn't a special stamp, but the Belgian Proof Master must have authorized the >>Express<< Stamp and evidently, no other Belgian Rifled Barrels, less the Belgian Express Rifled Barrels, were admitted into German without reproof?

Hochachtungsvoll,
