What is a Normandy 1959 clarinet worth?

The Normandy clarinet was never named as such by Leblanc. They are a mid to late generation Leblanc clarinets. The only Normandy instrument Leblanc made is a saxophone. This name could be associated with the Normandy band name used by Leblanc in the 60s. Normandy clarinets are not particularly valuable, the value is comparable to other Leblanc clarinets.
