This is a model of a Massey Harris tractor from
the late forties. In the late fifties the Massey Harris company
merged with Ferguson to make Massey Ferguson. However never mind the
fact that late examples of this toy had Massey Ferguson decals this
tractor is not and has nothing to do with the Ferguson tractor. Most
pictures you will see of this tractor in real life will have crop wheels
and look a bit like a three wheeler. They were made and sold on the
other side of the Atlantic.
However, Dinky, bless them, kept this antique in the range from 1948 through to 1971, twenty years after the real thing had gone out of production. This is an early example with metal wheels and a metal driver - in later models plastic takes over. I'm pleased with this example, it's really close to one I owned as a small boy in the late fifties / early sixties except that mine and all my friends' ones had either the driver's head broken off, the tow hook, the chimneys or all three, never mind bent axles.
This is a rare survivor.
