This is a 1929 Instruction Book for German Model A cars and trucks including both the large and small bore engines sold in Germany by Ford. These cars were produced before Ford's move to Köln.
The copyright date on the inside front cover is 1928 Ford A.G., Berlin, however the printing date on the rear inside cover is 1929.
The illustrations in this Instruction Book show a mix of 1928 and 1929 Model A features such as early light switch, double venturi carburetor, and LH hand brake on the truck, however it also shows the center squeeze hand brake on the car and the later single disc clutch.
