Spanish?

[Yannis]

Hi all. The black sheep is back in the flock. My public apologies because I had caused a great deal of upset to the moderators. Sometimes you cannot avoid history when you talk about weapons. I don’t continue because they will lock the thread again.

To the blades now.
I suppose this is a Spanish dagger. Please tell me if I am right and please guess its age. There is something strange in a hole in the blade. The blade is plated (I think later).
