This fun wooden toy was mine as a child and was so much fun to take apart and put back together!  When put put together it is 24\" long and is 12\" wide.  There are 7 wooden circles for each side that are different colors and sizes that effect how the toy will roll when put together.  The bar in the middle also comes out.  This toy is old but has a lot of fun left in it.   What a fun piece of Americana.  A great item for toy collectors.
