hypothesis that the Datsun was not a copy of the Austin. Other websites have pointed out that the decision to not press charges might have been because that by then the Datsun designs had begun to differ from those of the Austin. The 1933 Datsun Type 12 was a small car produced by the Nissan corporation. The name Datsun was used by DAT for their line of small cars. After the DAT corporation was absorbed into Nissan, these cars continued to be produced, and the original model name was maintained. The Type 12 was basically similar to the earlier 1932 Type 11, but had a larger engine. Japanese laws at that time did not require a license to drive automobiles with small-displacement engines. DAT/Nissan produced the Datsun Type 11 as their entry into this market. The original limitation for this class of vehicles was 500 cc displacement engines, but that was changed to 750 cc in 1933. Nissan responded to this change by producing a larger engine, and gave the more powerful car a new name, the Type 12. The 1934 Datsun Type 13 went into production in April 1934 with its chassis built in the Osaka Plant of the Automotive Division of Tobata Casting, which merged with Nihon Sangyo Co. (Nissan) after selling its factory. Its grille was chrome plated with a tall heart shaped opening instead of the Austin 7 like grille. It is the first Datsun model to have a truck variant called the 13T, along as being the first car exported from Japan; a total of 44 vehicles were exported to South Africa and Australia. The 1935 Datsun Type 14 is externally very similar to the Type 13 but uses the addition of a leaping rabbit emblem at the front. Mechanically, the old DAT engine of the Datsun 13 was replaced with the Datsun Type 7 engine, a side valve four-cylinder engine with a displacement of 722 cc (44.1 cu in). It marked "the birth of the Japanese car industry" according to Britain's National Motor Museum at Beaulieu. Nissan produced the vehicle at Yokohama, along with its commercial truck version called the 14T. Type 15 – 17 The 1936 Datsun Type 15 was mechanically very similar to the preceding Datsun Type 14. The Type 7 engine was retained, by with a higher compression ratio, increased from 5.2 to 5.4, which increased power by 1 hp (0.75
