Hi, I guess I'm another guy who thinks he has a rare violin. I have found an old violin left by a family member that contains the following info on the label: NICOLAS AMATUS FECIT IN CREMONA 1658. To the right of the label is a circle with a starburst around it. The circle is divided into 4 quadrents. In the top left is the letter "R", In the top right is the letters "SCH.1", at the bottom left is the # "18", and in the bottom right is the # "80" The bridge is marked "Paris" The color is right for the Amati family, the workmanship looks good. The sound is sort of mellow. The date is accurate for a N. Amatus. Has anyone ever seen an Amati with a label such as I described? May be a copy of an Amati. I do know that it has been in our family for at least 50 years. Regards, Walt.
