I picked up this Nickel 29-2 from one of the local guns stores last week. My question is about the lining of the presentation case. I don't think I've ever seen one in this color. Can any of you who are far more knowledgeable than I shed any light on this? Is it in fact a color that was put out by S&W? Considering the price I paid (under $800 before tax) I'm not really caring one way or the other... I'm just curious. Serial number places it as a 1980. Thanks in advance for your time.
