My guess is an unrestored typical European collector car. This would meet the normal criteria for a "Edwardian" tour car. I would guess this photo taken on a car run in the not to distant past.
The spare wheel on the running board is a rather common English treatment, by changing the wheel rather than the tire. Just remove the wheel on the car and leave the hub in place. Then slide the spare wheel over the hub tighten the nuts on the wheel bolts and you are off and running again. The Rambler cars of the era provided a complete spare wheel and tire assembly for replacement on the hub.
I can tell you, with absolute certainty, that it would look perfect in my garage.
Looks to be a 1911 with a 1913-1914 rear axle.
I can tell you it belongs to Neil Tuckett. I've sat in the car at Neil's place outside London. Great car. I took these pictures in Neil's shed.
I can tell you I like it. As a part time "Patina" guy it is wonderful. Especially against that white background.
Thanks for posting it
Royce, what is the cylindrical thing sticking out of the intake manifold?
That is a transmorgrifier.
Looks more like a flux-capacitor!
Don't you use a Mr. Fusion with a flux-capacitor?
Erich it is some sort of accessory "economizer" valve with a dash control. Many varieties of accessory like this were made for Model T's, they essentially are the same as a failed intake gasket when in operation. Which is to say worthy of conversation, but not good for performance! The whole point of such gimmicks was to separate the consumer from a few bucks.
