Small Silver Bowl 1900?

Bought this piece this week. Small bowl or drinking vessel measures 1 1/2"h x 3 1/8"w at opening x 2 7/8" at base. Have found several others but they were marked as attributed differently from Siamese silver to Persian, Indian and Indo Persian. Most had dates from late 1800s to 1900. Weight is 45grams. I hope someone will recognize the writing and markings on the bottom. I can make out 100% at the top and 3 at the bottom, the center wording I haven't a clue. Thanks,
Eddie
