Thanks for your mail to swissworld. I apologise for replying in English our Italian translator is away for a couple of days.
Unfortunately Manno doesn't have a webpage, and I haven't been able to come up with any details about it. The one thing I have discovered is the address of the municipio: maybe you could contact them ? Perhaps they would also know about the book you mention.
Municipio di Manno Via Grumo 6928 Manno/TI 091 611 10 00 Fax 091 611 10 01
I found it in the electronic phone book, which has one MUSCHI still living in the village: maybe he is a relative? Casa vitivinicola Le Orchidee Gian Carlo Muschi Strada Regina 6928 Manno/TI 091 605 44 76
