Silver Dish

[cmlindb]

I think the mano is the hand made portion of it and the AC is the mark of the maker. I the first link looks similar though in style.

It's a silver dish from Peru. Makers mark might be local but there have been American silversmiths like Truman Bailey who've marked Peruvian silverware.

I'm just not convinced it is Peru.  Plata (silver) or Plata Fina (fine silver) is often found on items with Hecho Mano (hand made).

My naked eye says it was a "trabaho peru mano"

yep....I had a Brain hiccup!    It does say Trabaho. 

Typed "Plata (silver) or Plata Fina (fine silver) is often found on items with Hecho Mano (hand made)." and meant to type - Plata (silver) or Plata Fina (fine silver) is often found on items with trabajo hecho mano.
