Thanks to all who all who responded. It's great to read those first hand accounts. Here's a couple more pix with some more identifiable bikes (all pix and the previous one from John Krausz's "The Bicycling Book" (c) 1982. All the photos themselves are "courtesy Beryl Burton" in the book.

and for those who still don't know who the excitement is about, here's Beryl's palmares:
12 Hour Record Holder: in 1959, Beryl covered 250.37 miles in a Twelve Hour Time Trial... That was astonishing, especially considering the road surfaces and the the equipment she was using; it was also remarkably close to the men's record. It was in 1967 that she took the big leap she knew she could do... She set off two minutes behind the men's national champion, catching him around the ten hour mark: she offered him some liquorice and went on to cover 277.25 miles/ 443.6 km in the twelve hours... beating the men's existing record by over 5.75 miles/9km.
