Rare? Compared to all those Howatts and Bears made over the years, heck yeah!
I know of a few Savora "collectors" locally as well as outside the state (even a couple in Germany), and they all tend to snap up Savora bows when they appear.
Ever see one on the auction site or in the classifieds? (Oddly, there is a Savora longbow at Stickbow.com as of 5/31 for 150 bucks)
When the Savora bow company went out of business, NW Archery bought all the equipment and Jay continued making them for a few years.
Duke Savora and Glenn were good friends and hunting buddies so that business deal was no surprise.
My good friend Wayne Fontenelle had Jay make him a custom one piece in the early 90's which he has used to take numerous deer and elk.
There are a couple ex-employees of Savora that frequent the sites and can fill in the details much better than I.
