G'day P38arover :)
That wasn't OLR-067 that you saw, it was Stephen Stansfield's "Norma Jean" alias OLR-065 :) it took out the Best Restored Military Vehicle, Stephen still owns that one, but has had ill health for quite some time now, James Taylor, the Landrover Historian and Editor of Landrover Enthusiast Magazine was most impressed with it :D as he had never seen an Australian Military Ambulance and they differ greatly to the U K ones.
cheers
