Sinhala / Sri Lankan Swords?

[VANDOO]

DANGER CONJECTURE AHEAD. THE JAPANESE AMBASSADOR WAS PRESENT IN SPAIN FOR TWO YEARS SO PERHAPS A SWORD COULD HAVE BEEN SPECIALY COMISSIONED AND MADE. HE MAY HAVE SEEN THE VARIOUS SWORDS FROM OTHER COUNTRIES PRESENT IN SPAINS MUSEUMS. THOSE ACCOMPANING HIM WOULD HAVE REPORTED TO THE KING ANYTHING HE FOUND MOST INTERESTING AND COMENTED ON. THE LAW AGAINST GIVING SPANISH ARMS TO A FORIGNER MAY HAVE BEEN BYPASSED BY HAVING A SWORD COMISSIONED ESPECIALLY FOR THE AMBASSADOR INCORPORATING THE FEATURES AND TYPES HE MOST ADMIRED WHEN LOOKING AT THE EXAMPLES IN SPANISH COLLECTIONS.
THE CARVING ON THE BACK OF THE BLADE AS WELL AS ITS FORM DOES NOT RESEMBLE A SIRI LANKAN KASTANE BLADE IT LOOKS MORE LIKE THE SPANISH BLADE SHAPE. THE DRAGON OR MONSTER CARVED INTO THE BLADE LOOKS MORE LIKE WHAT IS SEEN ON CHINESE OR OTHER ASIAN COUNTRIES POLE ARM BLADES. THE HANDLE IS CLOSE TO THE KASTANE FORM BUT A BIT DIFFERENT. THERE DOSENT SEEM TO BE A SCABBARD FOR THE SWORD AND THE ONE IN THE PAINTING HAS A SCABBARD LOOKING MORE LIKE A LEATHER EUROPEAN FORM THAN ONE FROM CEYLON. MOST KASTANE DO NOT HAVE A SCABBARD AS THEY ARE USUALLY MADE OF THIN WOOD AND ARE VERY FRAGILE. THE SILVER ONES HOLD UP BETTER BUT ARE OFTEN MISSING AS WELL. IF THERE WAS A KASTANE PRESENT IN THE COLLECTIONS IN SPAIN PERHAPS ITS SCABBARD WAS MISSING AS WELL.
WHAT WOULD PROVIDE SOME GOOD INFORMATION AND NOT JUST CONJECTURE WOULD BE TO HAVE SOMEONE FAMILIAR WITH FORGED BLADES FROM SPAIN LOOK AT THE SWORD AS WELL AS SOMEONE EXPERT IN SIRI LANKAN WORKMANSHIP. UNTIL THEN WE MUST DIG AND SPECULATE AND PERHAPS HIT ON SOME FACTS ALONG THE WAY .
I DON'T HAVE A PICTURE OF A BLADE WITH A CARVED MONSTER BUT INCLUDE TWO CHINESE BLADES A POLE ARM BLADE AND A SWORD.
