Wooden gudgeon (or plug) was put inside of the headtube to support the tube. It was believed that if the tube cracks, gudgeon would save the cyclists life. Mainly this was made because some of the races in France included stages with cobblestone roads. Pic taken from "Tidens Cykelbok - En handbok föt alla sorters cyklister". Thanks to 2Fresh.
