Salaams blue lander .. I'm not sure about the moon being a half moon nor of it being a man in the moon face though clearly the European style inscribed on Toledo blades by Juan Martinez and Peter Munch(Peter Munich) were "man in the moon faces"...I think the later inscriptions copied onto Islamic region swords were of the new moon. Your moon comprises a moon (presumably new) and 3 new moons and possibly a sun..Peter Munch used moons as Talismans it is thought...see http://www.vikingsword.com/vb/showt...highlight=MOONS
The reason for 3 crosses not 4 is probably because of the fullers preventing a 4th stamp being put. Three is a very powerful talismanic construct...in different regions including the Fleur de Lys 'Trio in Juncta' and Islamic forms.
