Here's a shot of what the Detroit News calls an 1894 Haynes...it's in the Smithsonian Institution. The model designation is not given. I can tell you with certainty that Elwood Haynes built his first car in 1894, and tested it on July 4, 1894 on the Pumpkinvine Pike just outside Kokomo, Indiana; about 15 miles from my hometown.
The car was actually built by the Apperson brothers, Elmer and Edgar, Haynes designed the car, and they built it under his direction. They formed an auto company together in 1898, and built cars until 1902. Then, the Appersons and Haynes split, and Appersons were built until 1925.
Haynes is also well-known for his alloy, Stellite; which is used in machine tools. Several variations of it are used in aerospace applications.
