Well, I think that I have now got the answer regarding the Autoculto “Junior” The donor has posted me the book that his father had with the machine from new, and it is the Standard Autoculto “Autogardener” instruction book, together with a well used copy of the Villiers manual for the Mk15 engine dated 1956, which engine it seems was used for both models.I now need a few bits to bolt on, like a Tarpen adapter and a cultivator frame etc.
