By the way, Gios is now made in the Far East, under a new owner, but the siblings are still building Gios's under the name Giostorino, copy right issue. The website is "http://www.giostorino.it/index.php" and if the year is under 1988, you can register your Gios! You can also email Marco Gios and he will answer in English(the web site is in Italian). Have lot of fun!
