As acquired 2751 had a tacho’ fitted, perfectly functional but of the incorrect type.
First port of call was Franco, again! He included the correct parts together with the other items that he let me have.
The tachometer I also thought that I needed was one of the striking Smiths instruments of the racing pattern with yellow numerals thus:
But it was not to be… This pattern of racing tacho’ did not exist when 2751 left The Works.
The last item is the tachometer mounting bracket. This was usually clamped to the right hand handlebar clamp using special extended studs. Drawings for the bracket and studs are held by the VOC.
David Dunfey kindly sent me a bracket he’d fabricated, to give me an idea. The bracket will need to be made, as it is missing. I may end up adapting the bracket that David sent me.
