I found this short blog post about him, wich also gives the names of other armourers from the XIX-XXth century.

Sadly, most of the very characteristic reproductions that can be see in many castles and palaces in Spain (Segovia has several examples) are nameless, but I think that they share a distictive style, different enough from historical pieces so it's easy to suspect their more recent date.

The workmanship is outstanding, and it's sad that this tradition is lost.

From the same blog, a video in Spanish:

I hope that I can do some research and get more information about this topic.
