It may look like something out of a sci-fi laboratory but the Sun Distributor Tester is a vintage tool we actually still used to test distributors on our classic vehicles. It measures the amount of time that the points in the distributor are closed (aka the "dwell angle") as well as the timing of the spark that is produced by the distributor.
Check out some detail pics of a distributor being tested and check out more of our specialty tools over on our webpage at the link in the comments.
