Paul Bonhop Toy Fire Engine Wood Puzzle from the 1950s

This is an interesting item and pretty rare. No current solds on Ebay or anywhere that I could find. It is Wood block puzzle by Paul Bonhop who made Children's toys in the 1950s. One of his items is in the Smithsonian Institution . It is much more interesting than current flat toy puzzles.  Given that this item might be missing a piece (the empty hole on the top left of the board) I started it out low on auction so someone can enjoy it.
