Set of three vintage pulling toys, 50s-60s

Set of three vintage pulling toys, painted wood, from the 50s-60s. A trailer truck, a dog whose bell rings, a couple of ducks whose neck alternately lengthens and shortens. Charming and decorative trio. In vintage state of conservation. With traces of wear. See detailed photos. The original tag is partially visible under the dog's body. The dimensions are indicated for the truck.
