Spanish dagger?

[Sajen]

Hello dear members,

This dagger crossed my way recently, I guess it's Spanish but would know your opinions about it, exact origin and an age guess maybe!
The handle from massive brass let become this dagger very heavy, the big guard is from iron, blade has a diamond cross section and has some serious pitting. The dagger is 31,5 cm long with a blade from 21,5 cm. The last picture show it with my Albacete dagger. All comments are very welcome!
