Does anyone know how the different Vintage Stetson felt lines equate to each other? In the vintage line up you have some that just say Stetson, others are the Royal, Royal Deluxe, Imperial and also the Premier. Then there are the playboy, stetsonian, sovereign and a few others. Now I've also seen vintage stetsons that say Stetson 20, or Stetson 25 and even Stetson 100. I know that the 20, 25 and 100 stand for the price of the hat at the time it was sold. But did stetson make a different quality of felt for each one of these lines? Or did they simply take a Royal Stetson and put a Stetson 20 on it, likewise did they take a stetson 100 and put an Imperial label on it? Art or Andy, you two are the ones most likely to know, but if anyone else has a clue I'd really like to know. I e-mailed stetson and asked but they haven't answered.
