The Army of Extremadura gave a Mercedes Prima to a child before surrendering. Since then, the artifact has been used to recount the memories of Republicans.

Fernando Barrero Arzac has spent decades documenting the history of all these families. He has now received the machine with the same task of keeping alive the memory of those defeated soldiers who, in the most difficult moment of their lives, bet on Octavio Gonzálvez's innocence. The end of the war remains an open question. The denunciations and accusations crossed during decades of exile reduced to pieces everything that happened afterwards.
