If it helps any, Bill Hannington was connected for years with the Reading cycle club scene probably as far back as the 1950's. I heard he initially built frames in Reading itself and supplied them to a local cycle shop - Buttrey's of Oxford Road who sold them with the shop's name on the transfers. I was dead lucky to buy one of these last year. Len Buttrey was president of my first club, Bon Amis CC with BH being, I think, a fellow member but I was only a teenager at the time and can't recall Bill Hannington. My neighbour, also a club member by coincidence did know BH - I'll mention your frame to him.
Best wishes,
Shaun
