Re: Can You Help With This?
Clean off that hub and look for a brand name. As Alajoyn said, it is similar to the early Sturmey Archer hubs but there is a difference in the way the linkage is attached. I researched parts availability for an 80s vintage Sturmey hub a couple of years ago and could only find parts through collectors but I was able to download an exploded view of my hub which helped me. Good luck, let us know what you find.
