Re Mk3 Vung Tau orphanage, If it is 178 128 it would have to be a Mk4, I think it is 170 128 or 178I, 170128 was recorded as being in vietnam, as to a full re-cab or partial hard to tell from that photo, it does have rectangular mirrors most early mk3's had round ones, all 6x6's in vietnam had rectangular mirrors as far as I am aware, the other give away to identify a full re-cab is the mesh cover over rear glass the Mk3 is a full cover and with full re-cab it is split.
