1988 International 3000 Series Model
Bus #800 - 1988 Thomas International 3800 school bus model. I say "Thomas" because to me the bus body looks more like a Thomas than anything else (excluding the rear of the bus).
This model was made by "Ertl" and was intended to be a showcase for the International 3000 chassis for buses, back in 1989. A very hard to find model!
