Cyclegod, I have been watching the one on ebay. Looks not too bad, but I might be in a bit of strife if another Elsinore appears in the shed.
Davey Crocket, I know where you're coming from and I would prefer an original seat, but a decent one seems to be pretty hard to find. I'm around 75kg - if I can find a decent seat pan, the moulded foam for the CR's are readily available, as are the vinyl covers.
Thanks for the feedback - I'll keep looking.
