Lot 610
c. 1935 Excelsior 350cc Manxman Project
Registration no. not registered
Frame no. ME 4770
Engine no. CX 1817
Although it had proved fast enough to win the 1933 Lightweight TT in Syd Gleave's hands, Excelsior's complex 'Mechanical Marvel' proved something of a disappointment thereafter, and at the end of the 1934 season the Tyseley firm opted for something simpler: the Manxman. A single-overhead-camshaft, two-valve design, the Manxman was built in 250, 350 and 500cc capacities. Both road and race versions were offered, though the 500 was only ever marketed as a sports roadster. Although it never won a TT, the Manxman enjoyed considerable success in international racing and the Manx Grand Prix, Denis Parkinson winning the MGP Lightweight race three times on the trot between 1936 and 1938. Notable Manxman developments included the switch to a shorter-stroke 250 engine in 1937 and the adoption (also applied to the 350) of an aluminium-alloy cylinder head with right-hand exhaust port.
There is no known history associated with this particular Manxman, the 'CX' engine number prefix of which indicates that it is a 350. There are no documents with this machine, which is offered for restoration and sold strictly as viewed. Key not required.
£1, 000 - 2, 000
