With the announcement of the Baillon Collection's uncovering in January 2015 and their consignment to the Artcurial auction at Rétromobile in February, it was decided that a small Addendum to the main three-volume work, Jacques Saoutchik, Maître Carrossier was warranted, since the find included three important Saoutchik-bodied cars. This small book includes: - A description with souvenir images of the three Saoutchik-bodied cars in the Baillon Collection. - Further account of Gijsbert-Paul Berk's time with Jacques and Pierre Saoutchik. - The remarkable discovery by Christoph Grohe of what must be the world's oldest chassis fitted with a Saoutchik body. - Information on a Saoutchik Cadillac parade convertible used by His Majesty King Hussein of Jordan. - Further background on the man who presented himself as Sir John Gaul. - More Saoutchik cars and drawings that have been uncovered. - Corrections and errata.
