did he buy it in China? If not the canes may have been made in China and sent to Italy where they were crudely assembled. I've got a lot of Murano canes that I've had for many years and have used in some work here in the US. I was in the Moretti/effetre factory about 25 years ago and they took me in their sample room and told me to pick out whatever I needed to take with me. Who knows how many others over the years have exchanged many of the murrine all over the world. I also had several from Perthshire as well. It has been a common practice for ages to sell and exchange many canes of different styles between glassblowers for many years. One 30' can make a lot of millefiore, and I've seen them pulled to over 75 feet.
