Wanted: 700c White wall or Gum Wall Tires

It was fiddy's tip originally I think. I was looking at lunchtime as I'm in the market for a pair of gum wall tyres suitable for commuting on London's famous London's roads.

PS they do exist in smaller a size, 23... and the older sort of 25 come up very small ... hard to find though. If you fancy some old 25s (look more like a 23 to me) I may be able to point you in the right direction ...
