I believe it was a spare or replacement from a mid to late 1978 March 77B purchased from Hewland. Identification number FT200-1192. Does not have the original March rear wing post holder end cover accessory. Side plated for inboard brakes and CV axle joints, and has provision for a oil diff sprayer. Has low mileage new crown wheel and pinion. Complete with centre throw out bearing assembly and assorted range of alternate gear ratio sets in tool box.
