Charles, 
 I am uneasy with the definition of marks as " arsenal" ones. Those were embossed stamps. 
 Yours are way more interesting: they look like private purchase. There are so many varieties of them, it is almost inavoidable to conclude that all ( or most) of them were made in different workshops. 
 The " golden" one has a date: 126? ( can't figure the last numeral). 
 If Hijra, it would be somewhere between 1844-52. 
 If Jalali, - 1881-90.

 Carlos, 
 
Seems to me the end of the scabbard was broken and a brass chape was added to fix the damage. That's why the scabbard looks much longer than the blade.
