Sorry, didn't mention the year because although the bike frame number defines it as 1962 it has been upgraded/modified over the years as many bikes have. For example this one has an 8' TLS front brake, external fork springs under the gaiters, a headlamp rather than nacelle and a twin carb head. The forks may be original 1962 with a modified brake, but I don't know. From what you've said though, and taking a good look at the seal holder it looks as if they are the earlier forks and I'll need the special tool. Thanks for the help as always. Cheers. Rob
