You may have to politely ask Ragnarok Metals as this may be a unique piece. The Link to the Website is up in the Sources. He has other wickedly awesome products available. This round represents just the second of three silver pieces of art from Ragnarok, formerly ffc-Texas. Cool stuff especially to stir the Viking spirit in your blood.
