I took my S&W model 53 to a dealer to test the waters in order to sell/trade. ( I mentioned this in a thread below). He told me that someone had attempted to cold blue the gun. According to him, a bad thing to do to the gun, making it undesirable to a collector. I couldn't really tell much difference in the finish until he pointed it out. He was not interested in the gun. I certainly have no intention of misrepresenting the condition of the gun should I decide to sell it online. What can I expect as far as a sale price? My objective is to acquire a S&W 357 with some help from the sale of the model 53. Thanks alot for helping a new guy.
