We could use some help here!
 

Please have a look at the attached shell guard of 2 ethnographic swords (probably from Bicol, Philippines, during the Spanish colonial period):
Are these recycled pieces or of local craftmanship?
Can their origin be narrowed down to a specific style/period/locale?

Here is the thread with more pics.

Thanks a lot!

These striated shell guards are similar in style to espada anchas (Spanish colonial swords in the Americas) which have been provenanced to Brazil mid 19th century. The belt hook is also a characteristic associated with these. Most interesting hybrid!!! and reflects the trade in outermost regions of the "Spanish Main", between the Philippines and South America.

In total agreement with Jim on this one. The striated guard with downward reverse 'hook' found on espada from Brazil and possibly other S Amer provinces? It is fascinating to see these hybrid types when one takes into account the trade routes of the Spanish and Dutch trade. Kai, that post has some excellent examples of weapons with cross-over appeal!
