Dubbed 'Manx Grand Prix' in 1939, what would become the best-known racing motorcycle of all time had become simply 'Manx' when production resumed in 1946. Norton's over-the-counter Manx racers were much as their pre-war counterparts, with single-overhead-camshaft engine, 'square' cylinder head finning, upright gearbox and plunger-suspended 'garden gate' frames. Only the presence of the Roadholder telescopic front fork readily distinguished them from the '39 machines.
The year 1949 brought the first significant change in engine specification, the Manx gaining a double-overhead-camshaft 'head like that enjoyed by the works bikes for many years, but the major development was the arrival of the Featherbed frame for 1951. The works' adoption of the McCandless-designed duplex-loop swinging-arm chassis the previous year had given the Nortons a welcome lease of life in Grand Prix racing, and Geoff Duke duly took both the 350 and 500cc world titles in 1951. The cycle parts remained essentially unchanged from then onwards apart from the adoption of a double-sided, twin-leading-shoe front brake for 1962. Manx engine development, though, continued steadily, latterly under Doug Hele's direction, until production ceased at the end of '62, among the most significant design changes being the adoption of 'square' bore and stroke dimensions for 1954 and coarser-pitch bevel teeth in 1957.
Nothing is known of the history of this Norton Manx, which consists of a 1946 engine and 1947 frame. The machine is presented in restored condition and would respond well to detailing (the engine turns over). Notable features include a 'pie crust' fuel tank; Smiths 8,000rpm tachometer; and an Amal TT carburettor.

Saleroom notices
The frame is additionally numbered 13166 (see online images).

The engine is of 1946 type but may have been rebuilt with a later short con-rod and barrel. The petrol tank appears smaller than standard and may be a modified earlier item. Other minor non-original updates are also present. Prospective bidders should satisfy themselves as to the specification and originality of the machine.
