Question of history: 1939 Standard E1 type
During WWII, from 1939 to 1945, Wilhelm Gutbrod produced in his Standard Fahrzeugfabrik, the freight three-wheeler type E1. According to forum entries, the design changed from a RR-layout to a FF chain-driven front wheel, like Oscar Vidal & Sons Tempo company did on their vehicles. As the forum user also "renewed" the nameplate, I really get doubt about the design change. As I don't get access to the book, https://books.google.de/books?id=7VGfvgEACAAJ or similar, I would like to ask, is there a reliable book source, confirming this change. -- Hans Haase (有问题吗) 11:26, 5 December 2019 (UTC)

 * Since you already have a precise idea of the source you want, you might want to ask that question at WP:RX. Tigraan Click here to contact me 10:42, 6 December 2019 (UTC)
 * Thx, at the moment I am not sure if the book really has information about and further research leaded me o the word "Einheits-Dreirad-Lieferwagen" as meaning of a design-standardisized three-wheeler delivery-vehilce. These innovation minimizing plans remembers to an unique design-standardisized truck, like Borgward produced, also Opel, a later GM subsidiary. Whats there about? -- Hans Haase (有问题吗) 11:49, 6 December 2019 (UTC)
