esa-aardvark,
It's a Vengeance all right (or, more likely, the US A-31 or A-35, as the vehicle is RHD [which in my generation meant "drive on the RH side of the road"], and it looks like a US Army truck).
Don't think it's being towed by the truck, though. The accepted way was to tow backwards with a dolly on the tailwheel. Never seen one towed from the front, although you could easily do it with tow ropes on the wheel struts.
It would be an awkward business, the man in the cockpit,having to steer with wheel brakes (and unable to see forward over the nose, or zig-zag along as we had to do with all s/e taildraggers). Perhaps the chap on the prop boss was shouting instructions to him.
Any provenance to the pic ?
Danny.
