An early "walking toy" which did just that when a youngster would hold the iron handle and tromp him around the parlor. I don't have to say wood toys are extinct...Benjamin Braddock was warned back in 1967 before he notched his college stick with Mrs. Robinson. Plastics.
Here is a brilliant idea for all you older siblings, uncles and grandfathers out there. Take junior down to the basement and show him a vice and a jigsaw. It will take 5 minutes, and despite the groans, you can point out the pause button first. He has never been to a lumber yard either...but the local craft shop might have a few slabs of pine.
