Mick, I can remember seeing a few of these as a kid but very rare now. Ever worked on them? Very clever hey. They used the 109” chassis. You can just make it out in the diagram. They ended up as a 110” but because they had a stronger floor frame piggy backing the chassis, upgraded springs and 9.00R16 tyres they were rated at 30cwt. IIRC that was exactly double that of a standard 109” Series II Landrover. The early ones ran the 4 cylinder motor and then later the 6 when it was developed for the SeriesIIA. A mates’ dad had one, which he left over on Moreton Island for fishing trips.
They sort of remind me of an OKA a bit. I know they were really heavy and I don’t think the military ever took a shine to them. The ‘70s alloy V8 101 FWC were a completely different animal, especially when coupled to a driven trailer giving an effectual 6x6.
And check this out. Hardly the basis for an Expedition vehicle but seeing as how you build race car trailers I thought you'd appreciate it. Maybe you could do this with a modern Jap truck like an FG or NPS. Haha.
It's obviously a FWC LR converted for Rovers race team. What else would you expect? Definitely a blast from the past.
