Sinhala / Sri Lankan Swords?

[Jim McDougall]

This is a falchion stated German from Stone (1934, p.224, #276) and stated 15th century. There is little information in text in Stone on this sword, its reference is shown as "A Cyclopedia of Costume or Dictionary of Dress" (James R. Planche, N.Y. 1877).

Please note the pronounced peak on this example, resembling this notable feature on the Hasekura sword. While the German provenance is of course distracting from our focus on Spain, and Italy, it is important to note that going through Calvert (1907, "Spanish Arms & Armour") there are profusely examples of German armour supplied to Spanish nobles and monarchs.
Armourers were typically actually 'brokers' and assembled harness components from many subcontracted artisans. With this they often furnished swords in many cases.

The 15th century classification is of course considerably earlier than the period we are discussing, but these blade profiles remained prevalent for many generations, even centuries with tradition bound Spain .
