When the owner contacted me, he told me that the bowl had been in his family since 1830 or before & I'm thinking "RIGHT" - marked sterling & made 180 years ago. I was pretty leary but after seeing it was actually sterling, it was too good to pass.
So now, I'm trying to figure a way to date it & (hope against hope) guess at where it was made & even figure out the provenance. I think it's an impossible task but the experts have come through in the past & any hints would be appreciated.
