I hear ya Mitch on keeping up with today's prices. Many factors and depends on the person, the day, and how bad one wants it. Hard to give a good estimate without seeing it. Did you have the gun in hand and get to examine it? Pics available? I'd guess it depends on what's keeping it from being 100%. Muzzle wear, dings, scratches, pits, buggered screw/screws, handling marks etc. and what area. Ex. I'd rather a little blue wear under the trigger guard than a scratch on the side plate. You state all correct so I assume correct stocks, and original box/paperwork. If minor wear or handling marks, $650 would be a nice deal but depending, could be up to $350 more.
