Walter Miller of the USA - a big name in car literature - sent us an intriguing series of mystery cars that we like to show you over the next few days. As all photos were printed from negatives of unknown source all pictures are of the family 'what you see what you get'. Are we looking at a Derby Bentley with a vintage 3 litre radiator, or what? The wings look very Bentley-ish at least. Please also check the curvy louvre treatment on the side and top of the hood/bonnet. This type of louvres may be the 'signature' of the coachbuilder.
