Baz,
The other alternative is to ring John Gillard at Classic Restorations.
John has tons (and I mean tons) of traction spares.
John can be contacted on 0207 358 9969, but not on Mondays.
He located at 636 Old Kent Road, London SE15 1JE
You can see some of the spares here:

(Ideal for watching on a wet rainy Sunday……)
Enjoy!
