The car ran at Bridgehampton in September, 1964, with Ronnie Bucknam at the wheel.
The car wore #97 and finished 2nd in Class, and 6th overall.
In that race, Miles drove
#98 (CSX2431), finishing 1st in Class and 4th overall...
Hal Keck drove
#62 (CSX2127) and DNF'd, loosing a wheel.
I can't find anywhere that Miles drove it at Watkins Glen; however, he did drive it at Elkhart Lake (with Morton and Scott) to a 1st in Class in 1964.
I'll post more comments on the "details" later...
