I have been speaking to a rather nice gentleman of 74yrs old his name is harold williams and he used to be a cattle haulier from moreton valance nr gloucester
the transport side is now closed but his sons run a hgv training school
his fleet of lorries included mack cadovers and in 1968 some of the first scanny 110supers (apparentley richard reads couldnt supply erfs with sleeper cabs
a big help goes out to all u chaps who have information or pictures of hj (harold) williams transport it would make him im sure very happy to see some in print
ps bubbleman i wouldnt put money on it that you havent got something somewhere
Have a look on the English Macks thread on here
Apologies, typing is not my forte - I believe that there are a couple of pics of the Mack that they operated on here, both before and after its accident
Hello Graham,as Ed said I put some pics of the Macks on that thread,Igot a pic of a commer maxiload somewhere which he had plus a 110 and a 140 Scania …somewhere 
Will keep a look out for them.

Hi Graham,
Was hauling to a chipping plant at Moreton Valance airfield 1969- 1971 when the last stretch of the M5 was being built. Must have seen those lorries, but can,t remember, its a long time ago.
