Ripon in "The Yorkshire Mammoth"
In 1938, Ripon was, in George Holley's estimation, a "city", as opposed to Thrsk, which was simply a "town". He pointed to the presence of traffic lights in Ripon as an example.

Dentist Aryeh Teitelbaum resided in Ripon. Wotan and Donner Rengaw, and Holley were all patients. When Holley worked on the mammoth named Old Bill, he went to Ripon to consult with Teitelbaum.
