| SPECIAL FEATURES of the G.{Mr Griffiths - Chief Accountant / Mr Gnapp} A.{Mr Adams} High tension Waterproof Magnetos Design. Silent running. Ease of maintenance. Maximum efficiency. Ease of dismantling & repair. Rotation both ways. All types of G.{Mr Griffiths - Chief Accountant / Mr Gnapp} A.{Mr Adams} Magnetos are fitted with : (a) an indicator showing, at any moment, the next cylinder to fire. (b) an automatic timing device. N. B. — The attention of manufacturers is drawn to the fact that by a simple adjustment the armature of any of the G.{Mr Griffiths - Chief Accountant / Mr Gnapp} A.{Mr Adams} Magnetos may be made to revolve in either a clockwise or an anticlockwise direction. MAGNETO type D 1 for Motorcycles 2 cylinders up to 2 1/2 H.{Arthur M. Hanbury - Head Complaints} P. This Magneto may be driven either at crankshaft speed (thus missing one spark at the exhaust and rendering starting of engine easier) or at 1/2 the speed of crankshaft MEASUREMENTS IN MILLIMETERS Type A B C D E F G H D 1 41 58 9 15.5 34.5 36.5 30.25 166 Type I J K L M N O P D 1 9.2 11.6 35 114.5 55.5 75 77 57 MAGNETO type D 2 for 2 cylinders Motorcycles up to 5 H.{Arthur M.
