Kindjal Arabic(?) translation help

[Klop]

dear members,

I got this basic kindjal which has what seems an arabic inscription. Some of the characters look like numbers to me but I don't understand why these are being mixed with letters and how to read this.

If it were only four numbers it would be easy to conclude a year, but in this case...

Can someone clarify what is written, are the numbers and letters meant as two different lines or am I on a completely wrong track?

Many thanks in advance,
Eric.
