Google "Turrero" pistols. They were "replica" handguns made in Spain about 60+ years ago, They are not meant to be fired. They turn up every now an again on auctions sites and their owners believe them to be antiques because they have been in the family so long. I have one as well, and think it would probably blow up if someone loaded it with black powder since the breech plug is only pressed into the breech. Mine is marked" R' Cuerpo de Guarde, de la Persona del Rey" on top of the barrel along with a very real looking Spanish crest. I suspect these were made for the tourist trade in the 1950s. Outwardly they do look authentic, but once you take them apart you will see they are only non-firing replicas.
