Cloth Seal, Continental, Wheel, Image & Held by Anonymous.
From a shipwreck off the English Coast*, ?mm.
*known to be carrying a cargo from Nuremberg and also from the area now known today as Belgium.
A-like structure, wheel countermark// anchor?
(the third image shows the rivet disc unfolded)
The general appearance is consistant with cloth seals from the Flanders area (Belgium).
It was speculated that the 'A' like structure might be the monogram of Hainaut but when the disc was unfolded this appeared less likely. See BSG.CS.01065 for a tubular seal with a similar mark.
