As you say there were many conversions to alternate uses in the colonies. Many of our restorations sat under grain bins in relatively dry locations and well away from ocean salt. These chassis' are most often conserved in great condition as compared to the Goslings well-eaten Thornycroft. However, on the down-side, it seems to me our chassis' are, more often than not, found rather battered, their rubber worn thin or missing entirely, and with bearings completely worn-out from hard use.
