Compare it to this "MEXICAN" 1933 Five Peso Coin.
1933 would be the same year the revolver shipped.
Compare these details:
- Both eagles facing left
- Five prickly pear pads (always five if Mexican)
- Eagle's head shape
- Right talon grasping snake
- Left talon grasping 4th prickly pad (always 4th if Mexican)
There are many versions of the Mexican Golden Eagle/Snake symbol, but this coins version and the Mexican flags formal Coat of Arms is the most common I've seen. I have no idea in what country these may have been carved, but they are clearly in a Mexican motif.
In my mind, the right stock panel is settled. Others will disagree.
