Jim is 100% on that.
When I first looked at your pictures, I thought there's something strange about that gun. I finally realized that it actually has proof marks! This is something somewhat unusual (in my experience) on Spanish pistols of this type.
For what it's worth that proof looks like one from the Eibar proof house and was implemented 9 July, 1931. Proofing in Spain was voluntary until around 1923, so maybe most of the Spanish guns I have seen were prior to that date.
