I just picked up a model66-2 round butt with a 2.5 inch barrel, the finish has been buffed to a high polish and the hammer bobbed with serrations added to the top of the hammer, It has a single action let off that is just scary,and a super smooth D.A. pull of between 5-8 lbs with No stacking crisp as a glass rod. I have a couple of people trying to buy it from me ,but I have no idea of the value. The gun was given to me by a friend trying to pay off a debt.Help thanks Karl
