Coffee pot of El Faisan, Sterling Mexico, 0,925

[Mario Galasso]

I've bought a coffe or teapot with these marks:
252811
El FAISAN
Sterling
Mexico
0,925

Someone may give me some notice about the silversmith, age of the coffee pot and locality of production, please? I've thought Guadalajara 1950-1978 but I'm not sure and I don't find this silversmith in the Encyclopedia or elsewhere.
