i've been serching this site & others to find the origen of these hallmarks on some sugar tongs i picked up, i'm sure they are solid silver as the engraving on them is quite deep & has struck no base metal, i'd say there mid to late 1800s by the syle & engraving, i bught these in Australia.
the first mark is " A&D " i'm unsure of the next mark & the last mark is an hour glass.
