1948 Canadian Nationals my dad was in 1st place after Ball had crashed his plane on day one. Ball and his wife picked up all the pieces to the plane glued them back together and came back on the last day to beat him out with a speed of 103 MPH. Ball won $500 and my dad won a Mc Coy .60 for a second.
Ball worked for Ford as a tool and die maker and had number #1 engine and my Dad had #13 paid a whopping $50.00 for that engine. The originals were all built at the Ford machine shop.
