Good evening gentlemen

I finally found a 1903 in a good shape in original caliber (sorry for the poor quality of the pictures)
And i wonder if somebody has ever seen this kind of mount.
The rifle was manufactured in 1907.
It will soon be given to Joel DORLEAC for a complete care

Thank you for your help
