Nickel guns do not always lend themselves well to pictures. Assuming the gun is tight and locks up well and the finish is not blemished I would go in the $800 to $1,000 range on a model 27-2.4", nickel.

Based on the blued extractor star and the “N” stamped on the back of the cylinder, it is most definitely a factory nickel. There should also be an “N” stamped on the right side of the frame under the stock.kBob:
I do wonder if this is a blued -2 that got nickeled after it left the factory....perhaps the barrel pin got polished down to the frame and then plated over?
