This is a replica gearknob of the one used in the James Bond movie “Goldfinger”. A replica Bond DB5 was on show at the Cornwall Gold tourist attraction near Redruth in Cornwall, England, for many years. It was never used in a movie but had been kitted out with all the Bond gadgets. This was a spare gearknob made by the guy who produced the gadgets. I understand the car is now in private ownership again.
