Hi Hughie,
It's interesting to consider the best ways to find information.
First, it helps to ask for what you want: so you're not "looking to find out all I can about a bike racer called tony godfrey who raced a Manx in the iom" but instead you'd like to contact someone who knows him? Fair enough. Sorry I don't know him. I live in Australia and don't know too many of the 65-odd million residents of the UK.
But here's the real suggestion: Tell us what you know about him. Tell us why you want to know more. Post some photos. Give us some hints. Get us interested.
You never know, people can sometimes help in unexpected ways (maybe someone lived around the corner from Tony Godfrey in Bitterne, Southampton in 1962), but in the absence of an interesting story don't expect too much.
Cheers
Leon
