Both the 320 and 170 V were in "European Custom Coachwork, Prewar" for some reason so we were up against multi million dollar cars. I'm not sure how the 320 won anything, frankly the workmanship on it was not that good.
Furthermore, I'm quite certain that this was a replica body. We have discussed this here before. I've been studying pictures of 320 Cab A's for some time, trying to determine whether it's possible to tell the replicas from the real ones. But seeing this car in person rather than on a low resolution internet photo made it pretty clear just how "off" some of the details are.
It was presented as being restored by Arthur Bechtel Co. and the car was purchased at Bonhams Monterey last summer with no mention in the catalog description about a replica body. Whether there was any mention of this at the auction, I don't know. It's troublesome to say the least.
