Hello all My name is jim and i am new to your site. I am looking for information on a revolver i bought at a estate sale. Here is what i know it is a Smith & Wesson model 27-2 .357 magnum. It has a 3 1/2 inch barrel and the serial number is S298144. the gun came in the original box and appears to have never been fired. I would like to know what year it is and is it a rare gun because it hasn't been used. Thank you for any information you can supply me with.
