Copy letter from Robert William Frederick Harrison to Messrs Wake & Dean Ltd, 110 London Road, SE 'With reference to your account for the table which you supplied to us early this month, we wish you to change the castors already on the table to a set which will raise the table from one to two inches higher. When this has been done, you will kindly render a corrected account which will be paid you in the ordinary course.' 29 April 1910
