Much as I don't want to stop the pillorying of Joseph Lucas, aha The Prince of Darkness, I should point out that when Dneipr motorcycle-sidecar combinations (WWII BMW copies) were first imported to Britain in the Soviet Union era, it was a popular modification to replace
electrical components with Lucas or Smiths equivalents to improve reliability.... A friend had one whose gears had failed to be case-hardened and it made it to 700 miles before the gearbox seized at speed.
