That is good thinking. It was actually Rory who initially boxed up and sent me the fork from Petworth all those years ago, when he fully had his feet fully under the desk at USE. I have contacted him occasionally over the years for the odd thing.Rory Hitchens was advertising loads of spares last year. No idea if he had any takers, I *think* they may have been free to people who could make use of them.
He's UK retro MTB scene royalty and an absolutely lovely gent to boot. I'm sure if you messaged him on facebook he'll help you if he can.
