Interesting -- I'd been calling it Aztec. It looks like a reproduction of the Piedra del Sol calendar from the Museo Nacional de Antropología. Either way, it's still Mesoamerican and that's what I wanted.
I agree with nofendertom that a glossy nickel finish would have made a more stylish and culturally appropriate choice, but Parkerized was what they had on sale on the day.
Big aside here: The connection between .38 Super and Mexico first came to my attention in the late 1970s after my dad finished serving on the jury of a local murder trial. A body had been found in an agricultural field with a bunch of FMJ slugs in his back and .38 Super cases scattered around. The convicted shooter evidently straddled the victim's body (his foot prints were found on either side -- he left lots of evidence) and emptied the rest of clip into him after his victim was felled with the first shot. The perp was an undocumented Mexican national, and he pled halfway through the trial in a deal to avoid deportation. Dad had never heard of the .38 Super, so I asked around the LGSs and was told it was a big deal south of the Rio Grande.
