I could really use a little information from some seasoned Colt wheel gun collectors out there. I have a chance to buy a third series nickel Detective Special that the seller claims is unfired. There's no box or paperwork and the seller does say there is a faint turn ring so I'm just curious what a fair offer to this gentleman might be. He lives a couple of hours away and I want to be able to work out a price before I try and meet with him to inspect the gun. Thanks for the help.
