Just over 150k serial range being an early 4th model. Equipped with a round bbl. A typical aged medium brown color to bbl and mag tube. Good markings. Rocky Mountain blade type front sight that looks like a blacksmith or gunsmith did the blade. Rear sight has also been replaced. The beauty of this gun is in the color of the brass receiver. It has the very desirable speckled butterscotch color to it. It looks like it has had a light cleaning to the metal leaving a mostly satin finish. There is a few dings and a couple of buggered screws but the receiver looks good! Wood is not too bad either. A slight sliver missing by the lower tang on the right side. Other than that, fit is very good.
