Thanks for the information. Stopped at the LGS and took a better look at this pistol. Hammer and trigger are not plated, they are color case hardened. Opening the cylinder, there was no N stamped on the rear face of the cylinder. Nor was there an N stamped anywhere on the grip frame under the grips. As usual, great information and an education for meandthe LGS owner as well. I told him to let the owner of the pistol know I am still interested. But that he woild have to ne willing to drop his price some because it appears that this is a refinished gun. So now I wait. Thanks again for the great information.
