Somebody recognises the maker?

[Zifir]

Is it possible to provide a picture from the correct angle (by rotating it approximately 180 degrees) and with better focus on the stamp?

Hallo Zifir,
This is the best photos (in different angles) that i could take.
Best Regards,
EFtihis

Since I was looking for a name, it took me too long to recognize that it is "imtehan" i.e. "test", or "tested" if you wish.

cheers,
