That is Bob Holt riding Ed Kretz pre war big base scout, FDB 381 at the 1949 Daytona 100 mi. race*. He took 3rd # 15 in 1948, 4th 1949. Kretz had Bobby Turner ride the bike the next day in the 200 miler. Bobby expired at 176 miles, placing 38th
* That was when it they ran it half on the beach and the road that ran parallel to it, by the late 40s it was just over 4 miles per lap.
Well the current owner of the Indian, Gary Landeen, managed to track down Bob Holt, and some of the subsequent owners, heres one of the photos he took of the 81yr old back on the same Indian 61 years between the photos, great to see.
