Tried Conways?
Hi Graham,
Have you tried Conways - no personal experience but they seem to always be mentioned when anyone asks about Series A spares. Next I guess there are some specialist seat makers - I was reading about a restoration in Classic Bike Guide the other day and noted that the guy had the seat rebuilt from a base only by a specialist.
Next I saw that Sammy Miller recently completed a Comet and Rapide (A) so might be able to point you in the right direction.
Finally, I'm sure you've tried the Series A specialists - Bob S and Bob A are the two I would have thought might point you in the right direction.
Regards
Stuart
Does anyone know if anyone is making them?
