Happy to see that you are finding those books worth your while.
The one titled "Las Mejores Piezas de Coleccion" is the standard reference book for collectors and antiquarians. It is very useful for establishing the origin and approximate date of manufacture of navajas.
I don't know if you noticed the large number of absolutely fearsome looking and large navajas without a blade lock; It tells us something about the enforcement of the anti-blade lock laws and also that most were nowhere as formidable weapons as we are told - Hey, what did all those fearless Barateros fight with?
This is especially so, if we consider that by the mid 1800s the majority of the navajas in use in Spain had French origins and for most part these did not have locks (look at the French pages and what turns up on e-Bay).
What I found even more interesting is that some time ago I came across an antique that had a ratcheting mechanical lock in the typical Spanish manner but the rear of the blade notch was filed back so that the knife would close under pressure on the blade. Presumably this modification was done so as to conform to the laws forbidding locks.
