Love those kind of toys.
Reminds me of the days when we made coaster racers for tracks that had
higher to lower runway.......
Then they went motor.

Also I did get some interesting presents from a company that made steam
engine boats....
Simple put puts.........
for my boys.......
Not exactly a working with wood model, but a model none the less to learn
about steam, and matches.

For the 5 & 7 year old grandsons. Got plans & parts (axles, wheels and
rubber bands) from a Meisel catalog several years ago.
