Welcome to the forum.
M&W is Mappin & Webb and these spoons were assayed in Sheffield in 1903/04. The reason that it is easier to sip from from the edges of the spoons is that etiquette demands that soup be consumed in that way. This site has numerous posts about Mappin & Webb, some of which may prove to be of interest to you; just put "Mappin Webb" into the search box and browse the results.
The fourth spoon, by GM&S (not known to me), was assayed in 1933/34.
