Thanks Tom - incredibly helpful
I was looking at the car earlier, it has the curved tube front axle, but the curve is not the same shape as the Franklin "curve". The more I looked at it today, with what you have told me in mind, the more it looks like a replica. Maybe based on a handful of bits including possibly the engine, but there is much about it that gives me a sense of re-creation rather than repair/restoration. Making such a thing would not be wildly difficult.
