BSG.CS.00288 — Cloth Seal, German, Seehausen, Altmark?

Found in Lincolnshire (not far from the Wolds/louth area), 44 x 32mm.

Eagle displayed, inscription around // blank

Identified by Michel Royer, "I do not know its attribution, it should be able to read the legend (ALT .... Altmark ?) but the representation is that of an eagle displayed (Altmark has in his coat of arms an eagle displayed)"

Maybe Seehausen, Altmark or Osterburg (Altmark)
