This is Ferdy from TopRun, Switzerland. He was driving for Wittwer AG at the time and the load is gold bullion.
This is normal on the Continent. Certain firms would be called by the bullion store at short notice to supply a tilt. They would load & go. In Swiss the driver has the option of carring a gun for the trip which can be to UK.
Hangartners used to do the silver bullion UK to Swiss in tilts.
although nowhere near as valuable, we used to load coin blanks and blank credit cards from de la rue to swiss and other countries (except italy thankfully ) and that was always 5pm booking for loading 8am next day and gone
