I believe David has a considerable amount of new information. Yes he spent quite a few years on this project. Years ago, he spent about three days here,doing research and typing into his laptop from morning until night. I also loaned him a lot of reference material. In addition, to all the usual Library of Congress/NASM/Institutional reference libraries and countless personal interviews etc, he thoroughly researched and sorted through the large lot of
EVR material that was uncovered in the 1970s. (The discovery of an entire trunkload of EVR's personal papers, albums, correspondence and family papers and contacts.) David also went into extensive detail of EVR's auto racing history and the Maxwell racers etc. I read what was ALMOST the final draft, about four or five years ago. But David just kept on digging and revising. He lives, breathes and sleeps EVR history. His license plate is "EVR." The wooden desk in his office was EVR's desk . When I visited him at Auburn-which has an INCREDIBLE aviation research library (much WWI) built on some famous aviation collections-I HOPE I talked him out of restoring/refinishing the desk. I was appalled that he would consider erasing all the little nicks and scribbles acquired during EVR's use of it. I think he left it as is. Much of the EVR material that belongs to the NASM is now in the Special Collections of Auburn University, due to his efforts. And I believe that Prof. Lewis was once a leading candidate for Director of the Smithsonian NASM. With all these years of fine-tuning the final manuscript, it should be a good one..
