The Smithsonian has an "Engineering Book", basically a record of cars built with some notes, covering January 1885 to early Feb 1891. As far as I know it is the only existing record of cars built. Itis assumed that there were other books, before and after, but if they survived there location is unknown.
It is held in the Archives Center in the Museum of American History.
The book is over 500 pages... Some cars are covered in detail... some there is little written. I have copied he entire book, so if the cars in question fall into these dates, send me a private message and I will look to see if they are included.
