Just a quick but blatant plug for Fabian's steel sprocket workmanship - it is truly outstanding and I am very happy with mine. It was fitted by my local Morgan Dealer and their service/parts folks couldn't believe the quality of the sprocket nor the weight, which is many fold lighter than the ship's anchor that MMC use right now. JFBI I say, even if it's for long-term stock (or indeed for a display case exhibit)....
