You can see where this started for me here
Well it took a couple of kindly members of the Mike Dolbear forum to have a new lug made and sent to me and another member getting all the lugs re-chromed. It's now finished.
Apart from the replacement lug and some tension rod washers the drum has been reassembled using the same parts it came with, including the calf heads. It all works despite its years of neglect and the complex nature of the internal mechanisms.
