Salaams all, Note to Forum~ Quote. "As the Karavas were the traditional martial race of Sri Lanka it is not surprising to find one of their symbols, the Makara, used as ornamentation on traditional swords. Such swords are unique to Sri Lanka and not found either in India or the Malay peninsular".Unquote
From this detail it is assumed that a historical search on the
Karavas could yeild clues.
Here are a few follow up web pages for Makara background~

Certainly what begins to dawn upon me during this exploratory research is how complex Sri Lankan society was developed...and the large number of separate Kingdoms upon which the Kastane sword influence could derive from.
