I'm pretty sure that's the Jack Stirnemann / Walker Morrison car, or at least that what it looks like to me. Go here, and scroll down near the bottom: http://www.huffreport.com/2011/kemp.htm
Full history on this car is in The Rodder's Journal #40. I saw the car on the Hershey show field and it looks just as good in person as it does in photos. Bob
