Is this a sirupate?

[JeffS]

Seeing photos of sirupate khukuris I've noted that they have a narrower blade than other khukuris types. However, I'm not sure if this class has other distinguishing features. This was an Ebay gamble, cosmoline covered blade and looked old with iron fittings in the photo but turned out to be brass fittings. Still shows age, must be from around WWII if brass fittings are a reliable age cutoff, otherwise I would think a bit older.
