It is already up in the marketplace, 50K gold on top for your efforts.
The masterwork Tatar Bow is in mint condition ;-), was only used during one generation of horse archery and for a brief period of time during my recent peasant years. It is a fine "submachinegun", bit weak, but fast, and great for HA or anti-archer operations. Since I prefer to hunt real targets and shoot other archers only in self-defense when the bastards target my woolen cap, I have no real use for it and will stick with the bigger bows.
I would prefer a MW Horn Bow (formerly Strong Bow) since I always despised it and would now give it a try.
But a Rus is also welcome.
Oh, and NO, my mw Long Bow is not for sale... still gotta shoot some people with it...
Update: sold it for cash
