hi, steve. nice sword. congrats! nacho is the expert on visayan swords. while waiting for his comments --
[1] i tend to agree that it's post ww2 given the scabbard tip's pointy design (my comment is not based on field research, but based on similar hilts 
here and 
here both of which sport the ww2 victory symbol);
[2] as to where the scabbard was made, i think it's still 
panay where the blade is from;
[3] presumably it had an extra long nose or horn; that would make it then a 
taribong, i.e., the 
talibong or 
sanduko used by panay highlanders called panay bukidnon; and
[4] as to the sword's name, based on nacho's info as posted 
here, it is called a 
wala-pilak taribong (i.e., a taribong that has no silver).
regards.
