Read the comments. They indicate that these are all disabled. However, 1 comment says that while they're disabled, the way the did it they can be easily re-enabled by using included parts. Who knows what the truth is. It sounds like the owner is a collector.
For those readers who doesn't understand spanish, the cache is composed ONLY of disabled weapons, but they're disabled under obsolete methods (disabling weapons changed across time in spanish legislation) so it is easy to bring them back to action with pieces included... Back then disabling only involved some drills across the barrel, not wielding locks or other vital parts. You can even see in some images cutaway guns (I saw an AMELI light machine gun used for instruction at 6:20 ie.
Mortar shells and hand grenades are deactivated (has no explosive inside) according to the speech.
Cache includes:
9000 CETME assault rifles of different versions
500 Rifles and shotguns
400 Handguns
300 Machineguns
300 Mortar shells and grenades
They had pieces to put them back into service, and tools to make forged documentation and change weapon numbers.
