That's so exciting! I did a little pony hunting in Italy once when I was on a school trip. I found a couple g3s at rest stops and some of the smaller more out of the way souvenirs shops. You might find some g4s at those types of places too. I've also heard there is a large flea market in Rome on the weekends where you could possibly find some vintage ponies but I wasn't able to get to it. Good luck! Maybe you'll find a rare Italian pony!
