Many-times British sidecar champion Colin Seeley bought Associated Motor Cycles' racing department when the company went into receivership in 1966. The previous year he had constructed the first Seeley racing frame to house a Matchless G50 engine, and the AMC purchase enabled him to produce complete Seeley G50 and 7R machines. The Seeley frame progressed from the duplex cradle original to the similar but lighter Mark 2 before the down-tubes were abandoned with the Mark 3. Production of Seeley frames was later licensed to Roger Titchmarsh and there have been countless unauthorised copies made over the years.
This Seeley-BSA was ridden by Bob Light's sponsored rider Lancelot Unissart. The machine's Seeley Mark 3-replica frame is believed to have been manufactured by two Peterborough-based engineers, one of whom was Pete Odell. The machine has a Roy Shearwood-prepared short-stroke engine (precise bore/stroke dimensions unknown), which breathes via a Dell'Orto carburettor and has Electrex World ignition. Other specification highlights include an oil cooler; TT Industries six-speed magnesium gearbox; Bob Newby belt primary drive; Maxton-modified Ceriani forks; Minnovation fork yokes; disc brakes (the front gripped by a 4-piston Sumitomo 'Blue Spot' calliper); and a KTM-type chain guide. The machine will require re-commissioning before returning to the track
