Like many others, OEC (Osborn Engineering Company) manufactured motorcycles using proprietory engines and gearboxes. The bulk of their workforce was drawn from otherwise out-of-work matelots. As might be expected with largely unskilled labour, quality was questionable and production haphazard. Annual output before the war rarely reached 300; most sold at bargain-basement prices.
In 1929 OEC offered sprung & damped pivoted fork rear suspension to complement their Duplex steering. From 1933, conventional centre-spring Druid girder forks became an option. The frame itself was a mostly welded twin top tube cradle type; a clear forebear of the McCandless featherbed frame of the 50s.
This machine boasts the potent 250cc Sports Python (Rudge) engine first introduced in 1938 (note the webbing on the drive side crankcase) mated with a period Albion internal positive stop 4-speed gearbox and clutch. Brakes are British Hub Co; 7” forged drum laced to a 21” rim at the front and 6” cross-over (19”) at the rear. Petrol tank is original OEC restored with a new bottom. Oil tank is period Montgomery Sports. All cycle parts have been refurbished with new bushes, bearings, fasteners, spindles, exhaust pipe and engine plates. Reconditioned mechanicals include cylinder head (new valves, springs and guides), barrel, piston (new rings), magneto (Lucas) and carburettor (Amal Type 6).
