Well this isn't mine, and it isn't Spanish, it's Brazilian. But it is interesting!

This is at the NRA Museum at the Bass Pro Shop in Springfield, MO. One of the displays was a case full of guns with serial number 1. Among them something I had never heard of, an experimental Rossi revolver (one of two made) built around 1972, a 4" .44 Magnum in Triple Lock configuration. I am aware that there were some Spanish Triple Lock copies made back in the early part of the 20th century (I have two myself, shown upthread) but this is the first I had ever heard of a modern version of the Triple Lock.



Because the gun is all blue including the third lock cam plate, the plate and its recess is difficult to see even in person, much less in the picture. But I did look carefully and it is there.

A little Googling brought up an article from the American Rifleman. Too bad the gun never went into production. American Rifleman | A Triple Lock From Another Place
