WE is a difficult maker's mark to be sure about as there were several makers with those initials working at the same time. We know that William Eley sent work for assay marked "WE" up to January 1797 (when he entered a mark with William Fearn). After 1797 there were several makers with "WE" marks:

William Edwards - from 11th December 1800, until at least 1823
William Ellerby - from 15th June 1802, until at least 13th August 1810
William Eaton I, from 19th March 1781 to 1801 (buckle-maker)
William Eaton II, from 18th May 1813 to until at least 22nd February 1840
William Elliot, from 7th September 1813, probably until 1825 at least
William Esterbrook, from 4th November 1817, until at least 16th September 1834

I have grouped together the four pairs of tongs below, because on examining the maker's mark, the mark appears to be the same. I have ascribed them to William Edwards because of the date of the first pair, being 1800/01. He was the only silver-smith working at this time except William Eaton I. The tongs could be by William Eaton I, who was a buckle-maker but we can't be sure. If the maker's mark IS the same then they must be ascribed to William Edwards.

As is often the case with these Georgian Silversmiths, we must caveat any ascriptions made. We simply cannot be sure.
