I'm researching a major British engineering group and am trying to put numbers to sites. Confusingly some sites have telephone numbers from two different exchanges.

Does anyone know of a map, descriptive text or website which identifies the geographic location/boundary of the pre-60s alphabetic exchanges - for example: CENtral, GERrard, LANgham etc. I know I can convert them to STD numbers, but that doesn't solve the problem!
