I didn't get anything either. There was a car company for a couple of years with Pitts in the name but they started in 1905. Also a steam tractor company, which may be what it is, but no definite results. I would think it was more likely to be some form of farm machinery as opposed to a luxury type of vehicle, mostly because the tag looks less decorative in nature. Great find and I hope someone recognizes it.
Possible, but from the link you gave, the company was allowed to change its name on Mar 23, 1903. The name may have still been carried for the first two quarters of that year.
