The Genuine Co (Lewis Turner)

I found an advert in the 'Kensington Post' dated 16th April 1920 (and other ads up to 1937): “The Genuine Co., 546 HARROW ROAD. 77 HIGH STREET, HARLESDEN. 364 EDGWARE ROAD. WE HOLD THE LARGEST AND MOST VARIED STOCK OF GRAMOPHONES AND RECORDS IN THE DISTRICT.”

I found this advert in the 'Kensington Post' dated 12th June 1964: “LEWIS TURNER (RADIO) LTD. 200 Portobello Rd., W.11, PAR 62211/4246.”
… and this one in the 'Hammersmith & Shepherds Bush Gazette' dated 12th July 1991: “LEWIS TURNER (RADIO) 200 Portobello Road, North Kensington. Tel: 071-727 6221.”
