Picked this one up along the way. The seller knew nothing about it except that it was brought back from the UK in the late 1940ies together with a gunong and a kukri (strange combination

).
From what i learned here:

This type of jambiya is called thuma and worn mosty by scholars and judges.
Hilt and sheat are most likely of german silver. The decorations are made from wire and then soldered to the surface. The blade has a triangular spine and appears to be massive. I don't see any traces that indicate it has been welded together.
What puzzles me are the marks on the back of the hilt. It doesn't look like language. I was hoping someone here has an idea about what these could mean/represent.
Best Regards,
Thilo
