I beg to enclose herewith application for Permit for Flashlight Advertising. I wish to inform you that the Flashlight Advertising Machine in question is the one which I showed to the officer of the Fire Brigade for inspection when I was connected with Messrs. Mason Company, Limited, which has its office at 29 Szechuen Road. Your early granting of the Permit shall be appreciated.

An application for permission to instal a flashlight advertising screen on the first floor verandah of the above premises has been received from Mr. K.S. Park, formerly of the Mason Company, Limited. The applicant states that the apparatus is similar to that for which permits were recently requested in the case of premises at the corner of North Szechuen and Range Roads, and also at No. 455 Nanking Road. I shall be greatly obliged if you will kindly let me know whether you have any objection to the issue of the permit.

With reference to your letter marked BS-10/341, dated January 11, 1927, there is no objection to the erection of this screen and flashlight provided that the lamp is ventilated and all the work near the lamp is adequately protected by some fire resisting material i.e. asbestos or sheet iron, in the case of the latter with a small air space in rear.
