This is the very rare model which was issued only as part of some Gift Set 20 Transporter Sets in 1972. It may, in fact, be the rarest Corgi that could have been purchased at your local toy store (as opposed to errors or unintended variations).
It is generally sound condition. There is paint missing on the edge of the roof and elsewhere to a lesser extent but the windows are intact, there is some suspension and the model is all original. One headlamp cover is damaged and the passenger seat is missing. This seat is identical to that fitted to the more common white model and easily fitted. As and when I find one I will attend to that but in the meantime the model is sold as it stands.
I have one other of these in very poor condition but these are the only examples I have encountered in many years of being closely involved with Corgis. It is difficult to put a value on such a rare model in any condition but I believe this is the sort of price you will need to pay and I am quite happy to keep it in my own collection if that is too much!
