A right-first-time design first introduced in November 1922, the overhead-valve 350 AJS - latterly known as the 'Big Port' - changed only in detail before being superseded by a much-revised M6 model for 1929. The latter's engine incorporated a number of improvements including enclosed rocker gear and dry-sump lubrication, while the frame was redesigned to accommodate a saddle tank, and Webb forks replaced the earlier Druids. Single-port and twin-port versions were available.
This matching-numbers twin-port M6 was purchased by the immediately preceding owner at Bonhams' sale of the Professor Fritz Ehn Collection at the RAF Musuem, Hendon in June 2008 (Lot 218) and then completely renovated. Works carried out included replacing the main bearings, gearbox bearings, and wheel bearings; re-spoking the original wheels; overhauling the carburettor and speedometer; replacing the oil feed pipes and exhaust locking nuts; and fitting two new silencers.
Following its restoration, the AJS was offered for sale at Bonhams' Stafford auction in October 2015 (Lot 222) where it was purchased by the current vendor. Since acquisition the magneto has been rebuilt (by Tony Cooper) and the machine has seen only occasional use. Used within the last six or so months, the machine is offered with a quantity of restoration invoices; some MoTs (most recent expired September 2013; a V5C Registration Certificate; a reproduction handbook; and some photocopied literature.
