Within the grounds of Amberley Museum, the Telephone Exchange is a working UAX13 complete with a rack of batteries, test rack & MDF with a full 50 lines of Strowger equipment. The exchange was originally installed in 1940 in Coolham. The building is packed with telecom related bits and pieces, even a Buzby carrier bag! In the centre of this photo can be seen a test section including a dial speed tester.
