Really? The African crate models are standard Taurus, eyewitness account. The model you are drawing was built sometime after Africa and before the 1963 World Champs, not a lot of time, hence the rather rough build of the original. It was likely to have been the proportional model at the '63 contest, but there does not seem to be a recognisable picture of it until after then, ie on the Carrier. Trouble with all this supposition is that we need someone who was there to give the definitive answer...
