Mike,
The return on the original entry pipe is worn almost foil thin. If I remember correctly, Wallace Gusler (the owner at the time) speculated that it was faceted and had a thumbnail. When I made my copy, I also included a band across the tail. This was probably back about '04-'05 at an early Richmond, VA show. It was really enlightening to be able to hold the original. He also speculated that it had carving behind the entry pipe that was similar to the tang carving. His speculation was good enough for me so that's how I built mine.
