This model was a 14 seater station cart. It used a 2 cylinder L-head engine of 3167cc with a bore and stroke of 120x140mm. Chain drive and magneto ignition featured as on other Sunbeams of this period.
The 16hp sold for £465. It weighed 30cwt. The wheelbase was 10ft and track 4ft 6in. The description of the chassis sounds remarkably similar to that of the 35, so I suspect they used a common chassis.
