Well, you may not know the name of the maker, but I am giving you a point for your Sherlock Holmes-like detective work on the office location and who works in it.
The building pictured is the Motor Sport Competitions Office at the Goodwood Motor Circuit in England where a certain part-time Autopuzzler works occassionally, when he's not trying to solved mystery car puzzles. His name appears on your list, so it's not Janet, nor the fishy one!
