Hi,

It's Portuguese, but close-ups of the marks are required.

Hey Trv, thanks for fast reply. except of very professional macro cameras, no phone can zoom as much to be a clear image as is very very tiny the hallmark. i have try it my best, and thats the maximum i can do... is appear to be a bird head and a B in a square... any toughts?.... thanks

There will be numbers under the bird's head, they will reveal much.
