Detroit Diesel did not even exist as a company until 1938 - so what's the deal with the Detroit Diesel 1-71 you mention?
And . . . what is a "flat top" diesel? Do you mean diesels with flat-top pistons? I've never heard the name before except in reference to some locomotives.
The earliest diesel engine on record was built by an English guy - Dugald Clark (or Clerk)in 1878. Obviously, it was not referred to as a "Diesel" at the time. It was a two-stroke diesel with a supercharger. It was his design that later led to the Detroit Diesel.
First compression-ignition four-stroke engine that was demonstrated to work (and later called a Diesel) was by Rudolf Diesel - in 1893. It ran on kerosene and showed a 26% efficiency. The one that he is better known for is his 1897 engine which is regarded as the first four-stroke diesel ready for production and practical use.
First diesel train that I know was 1912 in Prussia.
First diesel crawler tractor that I know of in mass production was the 1931 Caterpillar.
First diesel wheeled tractor in production was a Renault VY 1933 in France.
First diesel Mack truck had a Cummins engine 1933, but the first production Mack diesel truck was 1935. Mack had some diesel experiments starting 1925.
Detroit Diesel was formed 1938 by GM, and it started production of the 71 series - according to their archives.
