The recent thread on the roof mounted light and the discussion of white vs. black handles made me think of this relic I picked up many years ago. I'm thinking it wasn't sold for pro car use, as the tag calls it a "Sportlite", but it was made by the Unity Manufacturing Co. I was curious if anyone had an idea of it's vintage. The tag says Pat'd 1914 - 15 - 24 - 29, so I'm thinking 30s?
