hi simon it looks like the vehicle I saw a few months ago at Kallista in the dandenongs,I thought it was abugatti as I only caught a fleeting glance drool drool
It is truly glorious in the metal & the colour was indeed originally orange (this is as close to original as can be managed & from all available reports it's near indistinguishable from how it originally came).
The owner drives it vigorously & it is but temporarily in our museum.
Personally I prefer another Delage of his (also vigorously used) which we had six months or so ago.
