Wow-thanks for all the good info. I'm going to compare threads when I get home because now I'm thinking the threads are British! I also read Sheldon's site, but I am fairly certain it's a 78 because of the clear serial numbers. And yes it was made in worksop. This will be very good news. I also noticed yesterday that the fork ends are spaced less than the modern 100mm hubs. ANyone have advice on this? Can they be easily bent outward?
Thanks
