9-Igniter 

Drawing 800-Igniter is poor to read; I tried to make the best out of it.
There are an awful lot of parts, many of them bear either almost similar names, or general names, like washer, screw, terminal, HT., etc.
I jotted all data from the drawing down on the Excel sheet, those data which were readable, those of which I thought I could recognise them from Nerarar, Motoring on two Wheels and Instruction Book and List of Spare Parts. 100% Guarantee on correctness cannot be given. 

It is not clear if the flywheel hub is 931-Flywheel Hub Mark III or 958-Flywheel Hub. 

It is strange that the components of the Light Switch are incorporated in Drawing 900-Igniter, as the light and switch have nothing to do with the ignition.

It would be great if someone could provide me with a readable copy of Drawing 800-Igniter and detailed photographs, depicting all parts. Eternal fame will be his/her destiny.
