The pommel of course is the cat-head's-pommel we know from the sciavona.
Your sword is conform to a type of naval weapon which was used in 17th century by mercenaries of venice.
Typical is the cat-heads-pommel, the guard and a rather short blade.
So at first we have to define, what is a sciavona variation?
Which are characteristics of the sciavona? Most important characteristics of sciavona:
1)The cat-heads-pommel (iron, brass, rarely silver or other)
2) the blade must be fit for cut
3) a basket hilt
Do you agree?
My opinioin:
In remote sense can your sword be described as Sciavona variation (Pommel, blade). Presumably this was not a weapon used by dalmatian mercenaries, who were usually as foot-soldier in the service of Venice during the 17th/18th century, but startet their mercenary career as naval figthers during the Middle ages (Boccia). Probably there were dalmatians still in the navy around 1700 and used this type, but this is bold speculated.
I think, other figthers enjoyed sciavona variations - like us
