It is amazing what a couple more years development did in those days. One year you have a world record holder, then next you aren't in the running.
Of course Caudron was a major aircraft mfg and the Gee Bee's were made by a few guys in their hanger. Add to that the american fascination with bigger and bigger engines, and air cooling.
I have a hard time deciding whether a Merlin or radial sound better
