Strange you should mention the Dizzy tool, last weekend I visited a small private museum
http://www.wfkicehouse.org/newsite/ on a road tour with our MV Club main focus of the museum is automotive and mostly Ford including displays of Ford Dealership garage including the old work benches and parts bins. One of the tools on the bench was the tool head for setting up the crab head distributors (excuse the blurry photo flash did fire) but what will drive some people crazy are the parts in the parts bins.
