The only thing is, the box states it is from the Francorchamps 500 in 1963.
However, the Spa 500 kms in 1963 was won by Willy Mairesse in a Ferrari 250.GTO but it was number 36 and there is no mention of the word DROGO on the result list that I have access to. Number 9 in that race was a Lotus Elite.
Can anyone throw some light on this one, please?
