Wanted: Rossin 650c fork

For a frame builder it will be a piece of cake to modify a 700c fork into a 650c.
1/2 hour job, max.
I think that a 700c is much easier to find.
You've already planned to restore it.

That's an option I haven't considered. Thank you. Beeing not from UK, perhaps you can advise on frame builders in London, which would be capable of this? I'll give them a visit, when visiting UK :]
