This new series is designed to be easier to build for our younger model enthusiasts. When the handle is cranked a single offset cam has "Marmaduke" surveying his territory and his family. This would make a great science project for school combining the animal kingdom with basic engineering principles. Each model kit comes with: All wooden components shaped and drilled, Sandpaper for finishing, Paintbrush, Parts list, Comprehensive instructions. Glue is not included. The models are manufactured from renewable wood sources and are designed for age 5 and over. Younger builders may require the assistance of an adult. The models are not suitable for children 3 years and under due to the risk of choking on the small parts.
