Hello Sinner

The language is Urdu, the top line reads “ 400 bore double barrel cordite type number 3418”.

The person it was made for probably was not fluent in English so the local gun dealer wrote out the rifle’s description in his local language. The lower writing basically names different accessories in the rifle case.

The important date is on the lower left hand corner of the paper “ May 1918” which represents the delivery/manufacture date.

Hope this helps.

Aziz
