These ones I will explain:
A Stradivarius from the Medicis' house quintet
They called it the first upright piano in history, but it appeared to be a harpsichord
Some seriously blingy hurdy-gurdies
Really old detuners; labeled a "piano guitar", it has courses of 1, 2, & 3 strings - all of which run over individual moving nuts, activated by the keys on the lower treble bout: c. 1600s
Buskers in Napoli; percussionist has a set of various-lengthed PVC tubes, the ends toward him which he hit with rubber flip-flops minus their straps. they were good! (And a lesson for you youngsters: If you set up in a tourist spot where a 5 minute break will give you a whole new crowd, you only need 1 ten-minute number eady......)
