This is a Structo scissors lift dump truck with a wind up mechanism. It is from 1952 and is called a Hi-Lift dump truck. It measures 12 inches long x 7 inches wide & 5 inches high. The decal on the side reads - Toyland Construction Company. No. 844 - X77. Load limit 10,000 lbs and the one on the door says Structo Toys Freeport, Illinois USA. The windup still works but is sluggish - needs lubrication? It has been loved and played with so has some scratches and faded paint but it is still complete and in good condition.
