Spec.O.Nº. :
According to my theory, indicates the exact model.
Until now, you could not tell if the model was a WC-51 or WC--52, WC-56 or WC-57 and WC-62 or WC-63. O.K.?
You have to study the following table:

It is seen that these models have the Body Model: 66, 19 or 96, but does not distinguish whether or not winch.
Nor can know the distance between axles box.

I ask please that any of you translate into English.
Now, with the ratio table Spec.O.N º and model, we can know which model is exactly. If it is a wc-51 or 52, 56 or 57, 62 or 63. O.K.?
