* Condition: The condition of the instrument is the most important factor in determining its value. A well-maintained oboe with no cracks or damage will be worth more than an oboe that is in need of repairs.
* Age: Leblanc Normandy oboes were produced for many decades, and the age of the instrument can affect its value. Older instruments may be more valuable to collectors, while newer instruments may be more popular with players.
* Seller: The seller of the oboe can also affect the price. A reputable dealer or music store will typically charge more for an oboe than a private seller.
In general, you can expect to pay anywhere from $1,000 to $3,000 for a used Leblanc Normandy oboe. However, some rare or vintage models may sell for more, while damaged or poorly maintained instruments may sell for less.
If you are interested in buying a Leblanc Normandy oboe, it is important to do your research and compare prices from different sellers before making a purchase. You should also be sure to inspect the instrument carefully for any damage before you buy it.
