While the actual maker is still impossible to distinguish (the &B mark),
I can tell you that the other marks of S and EP indicate that this
is a silver plated Sheffield, England ewer made circa 1880 in pattern number 2082.
The S represents Sheffield and the EP means Electro Plate meaning the ewer cannot be sterling silver.
The maker &B would indicate 'and Brother' which could be any one of thousands of makers without knowing
that first letter since all makers used these other s and ep marks as a standard.
The silver plate circa 1880 English Sheffield ewer has a current value of $50 to $75.00 retail. This
price would be the same no matter the maker since silver plated items all have the same value range and are not so much dependent or valued on maker.
Some sites that I recommend for selling are Varagesale.com, Ioffer.com, OfferUp.com, Ebay and letgo.com.
You can also go to invaluable.com or liveauctioneers.com and search their directory for an auction house near you and consign to them.
