Please Help With Mark ID

Trying to ID this bowl which weighs just over 36 oz. Any thoughts or info MUCH appreciated!

Any ideas at all anyone?

Looks like nobody who might be willing to respond has any idea. It’s certainly beyond me.

Any impressions helpful. American? Not American? Age? Style? Use of “solid silver” wording?

English speaking, probably not American as it doesn’t say “sterling”.

Suggestion received. TY for trying!
