An Algerian musket ... and a translation needed?

[fernando]

Although i have been more into European stuff, i have acquired this Kabyle type musket mainly because of its lock; a large patilla (miquelete) specimen with a dog catch (calço atrás). I thought the brass decoration was only superficial but i now notice it is plated. The frizen is huge, to ensure enough sparking from low quality flints ... i would say.
The butt plate and stock decorations would be camel bone, as i was told ... and so beleive; it would hardly be ivory.
The punction marks on the barrel are certainly meaningless, with the 'commercial' intent to make it look Spanish.
However the marks under the lock seem to be Arabic caligraphy; possibly a name and a date, in my imagination. Could i have some help to figure out whether these are indeed Arabic letters/numbers?
That would be so much appreciated.
