Lead Crystal Bowl with Sterling Silver Rim (American Brilliant Cut Glass)

Understand this to be a lead crystal bowl, with sterling silver rim, acquired by grandfather (or great-grandfather) from an old Polish neighbor many years ago in Butte, Montana. Unfortunately, grandparents and father are passed, so this is based on my mother's recollection of what she was told.

It weighs 6 lb, 2.6 oz, with an inner diameter of 7 7/8" and sits 3 3/4" high.

Perhaps someone can tell me more of the makers markings. They appear to be a right-facing lion (or some other animal), an anchor, and an olde-English initial. And to the right of these markings is what appears to be the number 1790 followed by a capital “D.”

And can anyone tell me how one would describe/name the type of flourishing on the silver, and/or whether there’s a particular name or style of the carving design in the bowl itself?

Thank you!
