I had such good info researching the Pre Model 10 I just sold for an estate. Here's another one I'm trying to research, it's a Model 67-3 and has some features I've never seen on a Combat Masterpiece before. Fortunately it doesn't have the hole above the cylinder latch so it is pre lock, and it has a hammer mounted firing pin so I believe it still has a forged hammer and trigger not MIM. What is unusual is the heavy barrel as oppose to the pencil barrel I'm use to seeing on Model 67s. Also it has a round not square butt which is rather neat. The gun has been fired but is in excellent condition with perfect timing and a glass smooth action. Red ramp front sight and a plain blued blade rear. The rear sight by the way is fitted neatly into the frame and I beleive the frame is drilled and tapped under it. These rear sights I believe came in with the dash 3 series and really look better than the older style. There is no box or papers. What is the current market value in your opinion?
