Joe,
Well spotted on the photo of the K with the high air cleaner, I too have never seen one like this anywhere, was it a prototype which never went into production? looks like it was supported by a cast bracket, it looks far more elegant than the ones we are familiar with bolted to the "U" frame.
Well here is another British Wallis in the Cheffins spring sale on Saturday, this one was imported many years ago from Australia / New Zealand and was in the same collection as the first one I started this thread with.
This one is the second oldest known survivor on David Parfiitt's
www.steel-wheels.net tractor register, it is serial number 277 and one of the 22 known survivors on his list.
Being such a very low serial number my thoughts are this tractor in it's workinglife has had the smaller radiator and sloping bonnet (hood) replaced with the larger radiator and flat bonnet, especially working in a hot climate.
This did not detract on the day, keen interest saw bidding rise quickly and the hammer fell at £39,500.00 plus commission, it has gone to a well known collector of early British tractors.
Malcolm.
