From the link I would say that this definitely applies to both pistols;

"Chinese handmade pistol. Using features from Mauser and Browning pistols. Probably 1930’s-1940’s production. Very interesting design. Has many spurious German and Belgian markings."

During the inter war years when the Chinese Warlords were fighting among themselves , against the communists and the Japanese they were notoriously desperate for any arms they could get. To a very large extent they created the Spanish arms industry in Eibar and other parts of the Basque provinces. Many of those guns were copied by Chinese workers.
It is not unreasonable to think individuals may have been hammering and filing out their own copies to make a few bucks the same as in the tribal regions of Pakistan.
