Anne, I know nothing about this, but I've cross-posted your query to a Spanish-language list I'm on, in Argentina, but chock-a-block full of Peruvians for some reason, on Andean archaeology. The odds are about 1 in 2 that we'll get some response. (For language problems, get back to me if nothing else works.)
