With the announcement of the Baillon Collection's uncovering in January 2015 and their consignment to the Artcurial auction at Retromobile in February, it was decided that a small Addendum to the main three-volume work, Jacques Saoutchik, Maitre 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.
