Vintage Sterling Mexican ? Turquoise Bird Pendant

This early piece is 1 1/4" long and 5/8 wide. It is all hand hammered and signed on back sterling. Their is also a signature that is worn and hard to make out.I don't know if this is Native American or Mexican. I do know it is a very early piece. It was bought at an estate sale years ago. Thank You for L@@KING!
