If you own an early 1920~24 Matchless 1000cc V twin then this manual would be of great value to you. In 2 parts, firstly the maintenance required to keep the motorcycle roadworthy including tappet adjustment, retiming the magneto and adjusting wheel bearings, and the second part being a very important parts list. There are not a lot of illustrations however the list does show the Matchless or MAG (Motosacoche) I.O.E. engine, the gearbox and the rear hub with sprocket and brake details.
