I love Jay Leno's Garage site. He really appreciates the mechanics that go into a restoration. I mean the word mechanics in any sense you might think.
Here is a video where he interviews folks with vintage racers from around WWI. In particular, note the Model T racers owned by Ed Archer.
His 1915 Rajo racer was found in a backyard during the 1950's.
