Ian,
The fuller you mention on my sword is just an optical illusion caused by the lighting when the picture was taken. The sword has no fuller. By the way the sword you posted is absolutely beautiful.
Renegade,
I believe that this sword is definitely from the Philippines.
M Eley,
I'm glad you are interested in this type of sword too. Do you have any examples that you could post?
Battera,
I think you could be right about it belonging to a Katipunero officer and would be very interested in any more information you might be able to supply about them and the weapons that they carried. I have a couple more swords that I think were also carried by them and will post pictures of them as soon as I get my camera back.
Again I thank everyone for their help.
Robert
