Hi Alan,
You have a very nice Gentry quality sword.
The pommel is quite unusual; is there a piece broken off?
The blade of your sword appears to have a contrasting core or inlay running down the center of the blade.
From the appearance of this piece the hilt and wrap are old.
The Asang-asang (blade clamps) are interesting in that one appears to be made of Swaasa alloy.
