Many thanks to Tom Seaberg of Minnesota (USA) for his extensive help in compiling the information below.

N.B. After Massey-Harris took over the J.I. Case Plow Works Co. in 1928, some 20-30 and 12-20 tractors were still produced with the Wallis name on the radiator and the serial no. plate. These tractors are indicated by the "Wallis" name in brackets below.

The symbol next to an entry means that there are one or more photos of this tractor in the corresponding Photo Gallery - click on the symbol and you will be taken to these.
