This blade is certainly not Solo, but Madura?  
 
I just do not know. It might be, but if so, pretty recent --- it doesn't look recent, however even if we do allow recent Madura, there are more than a few things that are not consistent with that. 
 
I do not want to guess where it originated --- not from a pic anyway.
