Clearly visible Ferrari badges.
Ferrari 166 Spyder Corsa rebodied by Scaglietti in 1955. Special feature: oldest un-restored Ferrari?
That's it, yes, although my info said it was originally a 166 Inter rather than a Spyder.
I left the Ferrari badges as I thought it was so glaringly obvious it was a Ferrari anyway it just wasn't worth the effort to remove them.
It was just a matter of finding out that this Ferrari is not what it appears to be, as it is based on a 1948 166, rebuilt 1955/7 by Scaglietti as you say into this real beauty looking more like a 500 Mondial or later 250 TR; and it is indeed said to be the world's oldest un-restored Ferrari, although I'm sure there will be plenty come out of the woodwork to argue with that one!
Well done.
