1970's Scania-Vabis LS Flatbed
Seen at the Llandudno Transport Festival, North Wales, UK in May 2006.
Not too many of these around in the UK, I suspect it was originally a 6x4 artic tractor.
Bonneted tractors are not common in the UK as the our Construction and Use Regulation (C&U Regs) limits the overhaul length of the complete rig and a bonnet takes up valuable trailer space.
