From the Musée Baud site:
In our first room you will find music boxes, automata, clocks, singing birds, animated pictures and gramophones as well as other accessories, tools and souvenirs of the time period.
In our second room, one can admire the grandeur of our larger pieces while listening to these unique, priceless, mechanical musical instruments. Among the highlights include the famous "Maesto", an orchestra from 1900 comprised of 10 different instruments. Also in this room is the splendid "Phonolistz Violiona" playing solo violin.
