These have been borrowed from the Onward Holdings web site the driver of wagon being waved off is i think a old hand called Cyril Key iam told he was one off the first to go over the water i dont know if he is still kicking about i worked with Cyril when i first started at the firm he was a nice bloke.
He once told me that years ago one of the other drivers was messing about and left the handbrake off another unit and it ran into his putting a dent in the front panel, then when i found this pic there is the dint the other driver was a bloke called Kenny Beckett another old hand that was a pioneer of this industry funny tho he was potty as well
