Unknown blade with Arabic numerals.

[David R]

Good evening all, and I hope someone can give me a little more knowledge about the origin of this blade.
Last Weekend I was at a fair in Pontoise just on the outskirts of Paris, and my friend bought this blade off one of the stalls....
A fairly standard sabre type blade, ricasso, single broad fuller and a blunt false edge with a thread cut on the end of the tang. Photo below of it on the floor next to a metre rule.
At the base of the blade are stamped a set of numerals in Arabic on both sides. Not much to go on I know, but can anyone give me some idea of age and origin.
Many thanks to all, comments and suggestions welcome.
