I was on that expedition along with another REME VM , George Rodgers Temple . The regiment was stationed in Cyprus at the time and tagged this onto the end of an exercise in Libya. The one incident that sticks in my mind is the transfer box falling of a Bedford Rl because the mounting bolts sheared , this was before the strengthening modification was carried out, we ended up using cylinder head bolts of a scrapped American car in Sabba , when we left Cyprus 18 months later the box had still not been modified and still had the same bolts in it.
I also did another smaller trip later from Tobruk to Giarabub when we really did master the use of sand channels.
