What exactly is today’s Friday Lady driving?

Another view of the car as it is now.

I would like to make a comment on the remark by David Green about the originality of the car. In my opinion the chance that a more than 100 year old car is completely original is almost zero. Coincidentally a period picture of LD 481 circulates on the internet and if you look carefully at all body parts and compare with the actual situation, you will notice that many did not escape modification. The dash, the mudguards and also the rear part of the car on the period picture are all different in size or shape. The hooded dash is much wider. The mudguards are definitely different and have different curves. The fuel tank is placed lower and seems to be smaller in diameter, although the latter is difficult to see. The side light bracket was on the front of the dashboard, is now on the side. The bracket that holds the mirror nowadays, used to hold a speedometer. Moreover it is clear that the paint on the car has now definitively covered all originality, including the colour. The angle of the bonnet side however is still the same. This is logical as this angle is determined by the angle of the radiator side.
I still believe that the lead photo shows the LD 481 in some 'in between' stage, roughly halfway between then and now. How many De Dions of that model would have the same mirror and bracket combination on exactly the same spot of the dash?
I want to add: this is not about right or wrong. It's only about factual observation!

I am attaching a file photo of LD 481, which is indisputably a De Dion, and was described at Pebble Beach as 1909 BV Type de Course. Bonhams sold a 1909 SN Model G voiturette in the not-too-distant past, which is vaguely similar, but nothing like the same match as the Pebble Beach De Dion. The gear change tilts further forward; the scuttle is not the same shape (the SN in these voiturettes seems to sport a radiator within the scuttle, complete with filler cap); and I would argue that the rear hub cap is not the same as that on a De Dion BV. There is some variation in the SN's available in 1908-1910: sometimes the rear petrol tank is there, but more often not. So I still think SN is out. Having said that, I more convinced than ever that your De Dion is not LD 451. The bonnet cover is almost vertical at the scuttle, whereas the other slopes more. Second the scuttle has a narrower margin as it sits on the chassis, than LD 481. As I said earlier, LD 481 is said to be highly original. The more that small differences occur, the less likely it is that your De Dion is the same car.
