Silver Ewer with basin/filter - Ottoman with Tughra & ma

From my research I know that this is real Ottoman Empire Silver (usually 80%-90%). It was given to an important banker that played a pivitol role in overseaing the Bahgdad railroad construction. Photos show the assay and sahh marks confirming authenticity. It’s condition is pretty much perfect with no visible dents. I don’t have weight, however, not too concerned with that as I’m sure the value won’t be predicated ioff of scrap value (it’s very big none the less). If anyone has an inkling as to the value please feel free to comment. Thanks so much for the help
