Copy letter from Robert William Frederick Harrison to F W Lanchester, 53 Hagley Road, Adgbaston, Birmingham 'Dear Sir, Soiree. Referring to your kind promise to exhibit some models of aeroplanes at the Ladies' Soiree on June 24th, I do not wish to press you, but, as time is running short, the exhibit would take up, and the general requirements in connections with it. I enclose another schedule which perhaps you will now fill up and return.' 18 June 1909
