LEYDEN GEBLAEVT MIT. WEE( D) OF PAS(TEL) // missing but partial lion rampant on rivet stub

From Herman Kaptein via Peter Eggers, "LEYDEN GEBLAEVT = dyed blue in Leiden ... blue with weede or pastel" (weede is blue dye) in WLJ de Nie, The development of the Northern Netherlands textile dyeing industry from the fourteenth to the eighteenth century, I read:
p. 69 "After 1585 one often finds the expression 'pastel' for weede in the Leiden hallmarks"
p. 104 "In a 1585 ordinance on the blue painting of bays, only 'weede or pastel' was allowed
p. 109 "In a 1726 communication about weed we read that the weed from Erfurt was sold in barrels of about 300 pounds and that weed from Spain, France and England was traded in bales and usually bore the name 'pastel'.
The conclusion may be clear. That it was explicitly stated that the blue dye was 'weede or pastel' because indigo as an alternative blue dye was first banned and later allowed."

Weede is known as woad in England.
