In this area I'd think somewhat high. I saw one a couple of weeks ago an individual had for 400. Stainless with one barrel. He didn't have the barrel tool. The ventilated rib/heavy barrel will add to the value. Others on an Atlanta website sometimes ask up to 650.00. DW still produces barrels along with Eric at EWK.
Check completed auction prices on Gunbroker for max prices. Below is a link to the DW owners forum and EWK for barrels and tools, etc.

Good luck on your decision, they are good revolvers and very strongly built.
