DocBlues - Abear is pretty much on the money with prices.
New A+ mint, unassembed with original shipping cartons and original paperwork are at the top end of the collectibles.
If a particular Signature Bow was owned by someone historically important, e.g., Glenn St. Charles, Charlie Kroll, etc, and that number was originally assigned to that person with the associated paperwork, that particular bow could logically bring an additional premium.
