Help with this dagger

[fcoghm]

Hi, first of all sorry for my lack of experience. I'm just learning about this great topic and definitely in my first steps.
Congratulations for this amazing forum that has been very useful to me in order to understand better about daggers.
I'm just starting my collection and the following dagger was offered to me, but I have many doubts about its quality, age, origin.

I'd appreciate a lot your comments and sorry because the quality of the pictures is quite bad (didn't get better ones).

Thanks in advance.
Francisco
