55 Fordson Power Major Tractor with original boxThese can be easily confused at first glance. 55 is the first Fordson with headlamps attached to the sides of the radiator grill. It also has fixed axle steering which is a bit unrealistic. The next model is 60 which has headlamps inside the grill and a nice parallel type of steering. Later the Ford 5000 will appear as 67 with jewelled lamps. Luckily thats blue and grey so easy to spot! (Interestingly, the steering reverts to fixed axle type, though.)
