The box shown here is for the Dinky Toys #985 Trailer for Car Carrier model.
It is a (Large!) 'Supertoys style, lid & base type 'stripes' box which is complete with all 3 of the model locating inserts.
This model was also sold as a set (together with the Car Carrier) as #983. We can also supply the box for that set. Please see our #983 listing.
