I have a curved Antigua Winds soprano that I might want to sell or exchange in the near future, and I don't know what model it is or how to price it. The only identifying information I see is the serial number L699xxx. I bought it new from Junk Dude perhaps two years ago. I see people talking about Q models, etc. This one has no other markings that I can find and any help help with this would be met with gratitude.
