I have a Dan Wesson, ( no and in between) .357 15-2VH.
I paid $200 for it in 1980. Probably worth $350-400 today.
Here is one on GB with an eight inch barrel going for $500 currently, Dan Wesson 44 Magnum Gorgeous ! : Revolvers at GunBroker.com
Here is the main link to them on GB, with there only being five right now.

I would say if its as good as you say, it may be worth $750+
It is a safe queen, but it would be the last firearm I sell, and it would have to be for ALL the tea in China.
