Designed and manufactured by Mike Satur this design utilises a grease nipple to allow the shaft to be lubricated and prevents it seizing in the gearbox casing.
This type of failure causes the lever to overload the slave cylinder and it also fails due to the internal seals failing.
This was originally developed by Mike Satur and is still in production some 15 years later. The arm is laser cut and bent and the shaft is precision made using CNC equipment to maintain the accuracy.  MIG welded on accurate jigs with each thread checked after the welding operation. These are supplied with an angled grease nipple and a new clevis pin/R clip.
Every shaft is checked for fit and tolerance.
NOTE  Because the top section of the shaft protrudes from the gearbox it is likely to suffer from some sort of atmospheric corrosion, especially in the UK . This will not affect the operation of the shaft if correctly lubricated. If you are concerned then purchase the stainless steel version or clean and polish the mild steel at service intervals.
Beware of some copies that are made badly and do not work as well or even don't fit correctly.
Still only £16.66 plus vat 
Also available  stainless steel versions. with s/s clevis pin and R clip
