A Machmeter will be one of the star lots of an auction of Concorde parts and memorabilia at Marc Labarbe in Toulouse.
The lot is expected to make around $5,623-7,873 when it crosses the block on November 3-5.
It was used to show the speed of the plane using measurements relative to the speed of sound.
Concorde's maximum speed was a blistering Mach 2.02. That's around 2,180km/h - more than twice the speed of sound.
Another Concorde Machmeter sold for £32,900 ($43,556) in a charity auction held shortly after the fleet was retired in 2003.
