Thank you Jose. This one: 
http://www.vikingsword.com/vb/showth...highlight=itak Spunjer sold some time ago (nice one, see it to late and was sold already) is a later one, still have this form of ricasso but not distinct anymore. 
I think that Robert have seen and handled much more Tagalog itak, would be interested what he think about this theory.
Regards,
Detlef
