I always thought that the Shew flugel had a yellow brass bell and that gold was not an option. I was at the local music store and the tag on the 6310z said it had a gold brass bell. I checked the model on the horn and tag and it was 6310Z not 6310ZG like I might have expected. It did look like it could have been gold from the colour of it. I checked the Yamaha site(s) and found some conflicting information. Canadian site: http://www.yamaha.ca/show_model.asp?modelId=628&modelCode=YFH-6310Z US site: http://www.yamaha.com/yamahavgn/CDA...2400%26ATRID%3D20%26DETYP%3DATTRIBUTE,00.html I realize that on the US site it refers to the 631 on the 6310 page but it lists the correct bore size(631 is .433 no .413) Can anyone shed any light on this? Is it an option or is one site wrong?
