Shamshir, (number 2) translation and comments please

[katana]

Hi
Shamshir (number 2) , nice forged blade. bi fullered with, I believe, a Rhino horn hilt (hot pin test gave 'burning hair' smell).

I would appreciate it if the gold script could be translated. Does the bi-fullered blade indicate possible origins ?

All comments and help gratefully received, thank you

Kind Regards David
