Copy letter from Robert William Frederick Harrison to Messrs Haden & Co, 123 Cromer Street, WC 'Gentlemen, There is a leakage at one or two of the joints of the hot water pipes here and I should be much obliged if you would send someone to examine them and give me an idea of the cost of repairs. One of the coils requires a new stop-cock, but this, I take it, is a small matter.' 24 May 1909
