So far Joe this is the only original copy of the Gaurantee I have found, so not seen one signed or with a tractor serial number written.

I know from the 1970's through to the late 90's the only surviving British Wallis in England was rescued by the late Derek Hackett and then sold to the late John Moffat and became part of his Hunday collection which then sold to The Stapehill Museum and then sold into private ownership in the last ten years or so, I had confirmation from Derek many years ago that this tractor did not have a Guarantee Certificate with it when he found it derelect.
We now have more recent imports of both styles of the British Wallis from down under and I have not heard of any original paperwork with them.
