SOHC LH Timing Side Mainshaft Nut - Manx

- Timing Side left hand thread mainshaft nut. I had a small batch made like this, which were copied from one off a pre-war magnesium Manx engine I have. Not sure if this is original - but a bit lighter and they look nice! - Fits all SOHC engines - CNC machined from solid high tensile EN8 round bar (as high tensile imperial hexagon bar is getting very difficult to obtain)
