Ah, I forgot to note that pre-1924 Belgian >>Express<< rifles were subject to proof parallel to the German Rules, but there wasn't a special designated touchmark for the effort. Also, proof of other such rifles exported to Germany just are not mentioned. Possibly non-Express Rifles were not exported to Germany, but that sounds suspect. Information surrounding Express Rifles, and rifles in general, exported to Germany is wanting as well as lacking in the complex era of Belgian Proof Rules.

Hochachtungsvoll,
