John & Cody - If you are serious about owning one, save your money for a nice first year Type I Bear Takedown, either an A or B, what ever you like best.
Risers like the ones listed on the A & B Serial Number threads are the ones you want to own. They are the ones that are truly collectible.
All the later T/D Risers with green stripe, blue stripe, etc., can not hold a candle to the originals for their collectability.
While these new ones may function just fine, their real value will never be more than a fraction of the originals.
