It is such a shame the company had the fire losing forever even this type of information. I wish I had saved the company literature from back in the '60s and early '70s. It was not plentiful, seems the British companies either were skimping or left it to the importers to print. With the fire and loss of company records and history it would not surprise me the literature may not be some of the higher valued of all audio equipment literature, never researched.
Yeah, the company has quite a history. The key players back in the day, who were there long before even Raymond Cooke, were employees like Bill Escott, Ezra Broadley, and Arnold Hatton (Hatton, along with his wife, who was ALSO an employee there, would later play a pivotal role as Gilbert's eyes and ears in New York during the formative years of the longstanding Wharfedale/B.I.C. partnership... Hatton would apparently oversee the day to day logistics of the cabinet shop, the very-same one where the W*0 models were produced... He and his wife agreed to move there and be Gilbert's employees at large).
I know Gilbert and Raymond Cooke were solely-responsible for the SFB/3 model. It was the result of 3 months of intensive research following a few key prior events (those being the introduction of the Super 3 tweeter, the demonstration of Peter Walker's ESS prototype, and recent developments in the new-at-the-time foam surround technology).
Gilbert had a son, Peter I think was his name, who was killed back in the '40's when he fell out of a window onto stone flags twenty feet below. He was doing a project for Edna Briggs, his mother (Gilbert's wife). I think he was running some wiring up into the area he fell from, some little outdoor balcony-type thing, maybe to put music up there, or maybe just power. I can't remember. It's in the book.
I'm listening to my W90's right now. Dr John's "In The Right Place/Gumbo" MoFi two-fer CD. I forgot how great this sounds through the Wharfies. The horns, the organ, the background vocals, etc. I could listen to this all day long. They really nail that BOMP of a baritone horn.
