This is the version with suspension and interior, developed from 409, ad making the Jeep one of Corgi's long-running models which appears in several forms. This is just the basic form, with a nice plastic canopy on the back (which was not included with the 409).
There are several variations of this model. It was issued in beige with either a yellow or red interior and a this blue colour with either a red or yellow interior. Additionally, there may be normal shaped wheels like this one or the later cast variety, production spanning the period of change.
I think the plastic hook at the back will always been the grey plastic type found on several other models.
This is a superb example.
