Danish, Flour Bag Seal, Skanderborg, Image & Found by Graham Dale.
Found in Lincolnshire, 17mm.
Two towers with water beneath on one side and printed in raised letters on the other side is FLOR [ME]EL
Originally thought to possibly be German but meel is Scandinavian not German for flour and the finding of another example, BSG.BS.02056 led to a reassessment.
