Earrings - "Silver by tono"?

[think_tomorrow]

I buy bags/lots of mixed jewelry for crafts, and these were in my latest thrift store find - I know a little about silverplate marks, but jewelry marks are like hieroglyphics to me (unless it's something like Trifari or Coro). Any information about this mark would be greatly appreciated!

Okay, I feel silly, since the first result for "Silver by tono" gives me the name Antonio Pineda. The mark in question looks like one of the earlier ones, from 1945-1948. Does anyone know what the lower hallmark - the eagle with "17" (that's what it looks like to me, at least) might mean?

The Mexican governemnt stared issueing "eagle number" around 1948 to be placed on all sterling being produced. It was established as a mark to denote taxes paid, and that the item was at least 925 silver. #17 was assigned to Antonio Pineda
