Rick,
Welcome to the forum.
The gut reaction you are getting is because of blueing done to the barrels. Cold or hot does not matter. This has long been considered a "hack" job to hide the damascus. Once that is spotted the, whole "restoration" is suspect. Usually the chambers have been tampered with as well, which often makes the gun unsafe.
Some years ago, during one of my grouse outings, I stopped at a Gander Mtn store on the way. They had a lovely LC Smith. I asked to handle the gun. It became very obvious to me what had been done. The damascus had been blued. The "case colors" had been painted on. The whole gun was covered with a thick coat of varnish. I pointed this out to the sales staff. At first they could not believe it. They brought the gun to one of their smith's who confirmed what I had told them. They immediately took the gun in back and told me it was no longer for sale.
A reputable dealer can tell when a gun was "fixed" beyond repair.
With out having hands on, it sounds like wall hanger is good use for it. Which is too bad.
Hopefully Walt will chime in about how the receivers were finished.
