Culshaw & Horrobin's book has the same picture as '5hp, 1900'

You have greater resources than myself. It's almost certainly a 1900 5hp car, but I got confused by website information that claimed the company produced cars powered by petrol, oil and paraffin - I've just looked at my Beaulieu and although the car was titled Petrocar, it was powered by oil(!) which was a mixture of kerosene and paraffin. I thought "Petrocar" meant it was petrol-powered!
Thanks for the extra information. The point is awarded.
