All depends.... if a "rarer" variation, i.e. I bought a Simson police from a LF member, and paid more for it, you simply don't see Simson Police lugers. An artillery or navy reblue, you simply don't see them as often as a 4 inch, so folks are willing to pay more for them. If refinished well, then that makes a difference too.
To me, I would rather have a rougher shape gun than a reblue, but then you kinda get tired of that rough shaped lugnut and I can see why folks would want it refinished!
