Featured Taxco 925 Signed Fish Pin; Illegible Marks

This is 3 1/4" long, 1/2" wide; weight is ~10 grams. The back bears 5 marks: Taxco an' 0.925 at the lower edge; signature an' Mexico at the upper edge; the Mexican Eagle (pre-'56, delineated) at the tail V, but I cannot read either the signature or the 2 numerals in the Eagle...though they may be '33' or '39'. I will appreciate whatever assistance or comments y'all can offer on this wee puzzle!
Thanks for lookin'!

 

is that the Jesus fish ?

 

Just a fish, I think - no Greek letters in the middle (IXOYE or it looks like that - Jesus Christ, King of the Jews IIRC) . #89 in the eagle mark, if that helps.

 

It surely does...Thanks!

 

My understanding is the Jesus Fish swims left; the crossed lines of the tail are to the right.

The Eagle 89 brings up DELFINO, a Taxco artisan during the Mid Century era.

 

According to several people on eBay and etsy -- and other sites -- this is marked DELFINO. Everybody says Delfino is or was a noted silversmith in Taxco. But full name is never given, and I haven't seen any proof.

I'm linking to one from Ruby Lane in which the dELFIno signature is pretty clear.

Coincidentally, delfin means "dolphin" in Spanish.

You beat me to it, Fig...an' the RubyLane is a dead ringer for mine, except for theirs is an Eagle 3, for Taxco, so later than mine I believe. Thanks!
