With the demise of the Concorde fleet, spare parts from the scrapped fleet are to be auctioned at the Hotel des Ventes Saint-Aubin in Toulouse, France, from September 28th to October 1st of this year. Interested in buying a piece of history? Have a look through the catalog, and bone up on your aviation French to avoid accidentally buying an “arbre d’entrainement” (drive shaft), when you really wanted the machmètre (mach meter). The iconic instrument (which tells you the airplane’s speed relative to the speed of sound), sold in lots 310, 568, and 791, respectively, is estimated to fetch between 1500 and 2500 euros, but you can bet some aviation nutcase is going to drive the price higher than that. Even if you can’t attend personally, you can send bid orders online.—Jacob Ward
