Ottoman Empire silver bowl

I have an heirloom Ottoman Empire solid silver bowl, a namesake gift given in 1896 to my great-aunt by her great-aunt, who purchased it in Constantinople in 1870. According to a note handed down from my great-grandmother, there were papers attesting to its having been made around 1715.

The bowl is 2" high, 5" inches across at the top, and weighs 205 grams. It has a handle resembling a palm tree with a little bird perched on top. The outside of the bowl is engraved with designs of ten mosques. The tughra is on the inside, but I don’t know enough about those marks.

I would be interested in any thoughts or insights regarding this piece. I hope the attached photos are helpful. Thank you.
