Wartnaby and Draper of Coventry. Also as WD Ltd

WD was a motorcycle produced by them from 1911 to 1913. Also sold motorcycles through Service and Colonial

The company is formed by William Thomas Wade Wartnaby and Alick Darby Draper

Late in 1911, a machine appeared that was different from the rest. The engine was made by Monk Engineering Co. It had a pressure lubrication system with a gear pump submerged in the oil in the sump. Both main bearings, the big end and the gudgeon pin were force fed in an era when most still relied on a hand pump, sight bowl and drip feed. Other 496cc engine details were a separate cylinder head, both it and the barrel being held by three long bolts, and a front-mounted magneto. It also had Druid forks and belt drive.

The machine carried on in that form until 1913.
