Curiouser and curiouser....
it is left-hand drive. According to all knowledgable Wiki - the few LHD that were produced, mainly for the Dutch Army, but for the Dutch, they put the indicator lights on top of the light-box....
So who would want a military Lightweight LR (signals type) - non-British military, non-Dutch destination, European model that ends up in the middle of Saudi?
The underslung winch, I initially thought was a rather botch job - fitted at some later stage. However, Signals (cable laying) may have been "OEM" specification?
Also, the choice of tyres fitted are interesting - BFG (i don't think they were standard LR or Brit MIL spec) and judging by their wear they have not rolled that much (completely buggered by standing for so long in the sun)
