It is in the catalogs from 1910-1914 and did not reappear after the First World War.
On the left barrel, you can see the proof as well as the use marks. In France it's value is not more than 500 Euros.

Ted very well underlined (the problem). It was the gun makers who chose the type of powder, and also the charge of power in France (for proofing the gun). After 1923, this was no longer the case.
Dave I have sent you another picture via email. Note the difference on top of barrel. Later add appears to be Damascus as well.
