Fabian sent me one of his lightweight steel sprockets from Belgium. You would have thought this was courier proof, especially when as well packed as it was but no. It looks to have been hit with a spike of some sort with a huge amount of energy, which has severely damaged one of the flanges and may have cracked one of the teeth. In fact I semi-jokingly said to Fabian that it looks like it has been hit by a rifle bullet. It is going to have to go back to Belgium for X-ray examination and dependant on the results of that, repair or replacement. I am assuming that I will have to replace the hub with the later type since mine is a very early car.
