In reply to Andy Cloquet:
I have two guide from 2007-2009 but they are in italian. For the record, they are :
Masino Bregaglia, Regno del Granito by Andrea Gaddi in June 2007
Masino Bregaglia, Regno del Granito vol II by Andrea Gaddi in June 2009
They are both excellent guides. I bought them in a bookshop in Milan. I'm not sure whether the likes of Needlesports could lay their hands on a copy.
