Large Nuffield Universal Tractor (page 350)

As (3) but with a different box label, showing a line drawing of the model.

David Brown 25D tractor (page 351)

As (8) and (9), but this is a one-off model of the tractor originally owned by Eric Percival, Vice President and General Manager of David Brown Tractors (Canada) Ltd who died in Toronto in 1984.  It was found in his loft after his death, and it is thought to have been used as a styling exercise to show the new livery of the David Brown 900 tractor launched in 1956.  The hubs and grille were re-painted either by David Brown or Denzil Skinner in French blue to replicate the livery of the forthcoming 900 Tractor.
