LEGO 310 Motorized Truck Set Vintage Model Maker Samsonite 1969 Rare Incomplete

The LEGO 310 Motorized Truck Set was a 176 piece Samsonite set released in 1969. It consists of 3 model maker trucks with self steering, doors and a dump truck and crane. These are combined with a reversible power unit which can motorize any one of the trucks. This item is in good used vintage condition. It does have signs of wear because of the age and does not contain all 176 pieces. I can not confirm if the electronic part is still functional.
