Hi everyone, I am looking for some help identifying these sugar tongs. They weigh 68g and passed several tests suggesting they are silver: they are non-magnetic, show uniform color, leave black residue on a microfiber cloth (tarnish), and pass the ice-melt test. They also feature a professional "A" monogram engraving. Despite a very close inspection, I cannot find any hallmarks or stamps.
