1950's Atkinson 8x4 Lorry Mounted Crane
It was not at all common to fit cranes to what looks like a standard 8x4 chassis although the chassis may well have been strengthened using flitch plates.
This somewhat rare vehicle was seen at the Llandudno Transport Festival, North Wales, UK in May 2006.
Getting it the rally site may have been a little difficult as it is now illegal to move such cranes on the public road in the UK.
The owner told me his yard was not too far away and he followed his Matador to avoid any problems, hopefully there were no no low bridges on his route.
