I think I may have seen XL canopies on later 3 litre Telstra Patrols, but I'm not certain. Mine is a Rosscos. Telstra 4.2's, of my vintage at least were either Rosscos or Obeico. Fairly similar, but the Rosscos has a folding driver side door & the Obeico as a 2 piece driver side door. Each had a different design for the drop down twin spares. Both very similar though
