Yup there was a "chain" of lewis,s Head Office was in Renalagh st Liverpool .There was one in Manchester, Glasgow,Bristol, Leicester and I may remember some others.
Ownership changed over the years, at some point they belonged to the British Shoe Corporation and Charles Clore was the chief in the late 1960,s . Selfridges was also part of the organisation,which is where we did our managemnt training courses at Welbeck St London . There was/is a selfridges still in Oxford of the old stores.
