Antique Vintage Sterling Silver 875 Latvia Signed Tea Glass Holder 1920s? Riga?

Description

This listing is for ONE cup - Latvian Sterling, three stamps on bottom:
Woman in head dress with 875 in oval, woman with head dress and another mark that i cannot discern.
There is another stamp on the top edge near the handle, the woman in head dress. It appears that there may be another stamp near this mark, within the floral border edge. Please see photos. I have included quite a few images of the marks. There is some sort of mark, along the bottom trim base, I cannot tell if it is from metalworker tools, if it is a special mark, or what exactly it might be....please see photos.
This is a Latvian silver mark. It was probably made in Riga - I cannot guarantee this.
It appears to have been gilded inside. I didn’t do any extreme polishing.
beautiful workmanship, there is a monogram: B T is a beautiful Art Deco script. It is lovely!
Art Deco styling, likely made around the 1920's to 1930's - I cannot guarantee this.
