Marcos Maniacs

Howdy, I am new to the site and have a few questions. 
       1.) Did the early hoods (bonnets) not have air vents or the
indentation for the insignia?
       2.) Did the de dion rear axles use MGA ring and pinions? Were
the housings related to TVR or a Marcos only aluminum casting?
       3.) When did the mini wheel arches come about?
       4.) What happened to Wooden Wonders and Fiberglass Fanatics in
Sweden?
       5.) Is there anyone in the US or UK that does Marcos wooden
chassis work?
       6.) Is there a go to guy in the US for the 1800 GT's?

                        Any answers greatly appreciated. Thanks. 
                                                                 Charley
