early v8 rhd chassis #s

[55 flattop]

Have just brought a rhd 35 phaeton to add to my collection and am trying to find out its country of origin as it has a strange chassis # which is C4618072886F body id #54375 the vehicle is a mix of deluxe and std features it has a std steering wheel and no waterfall on the dash all other deluxe features are present it has parklights on the top of the front guards which suggest an english origin and a mph speedo canadian fords had a chassis prefix starting with C18 this number on the chassis # has the # 461 between it ? searching the web the C could stand for canada or commonweath built any help appreciated
