I drove 4.5 hrs in cold rain and snow to check out a blued 4 inch security six in the local classified section today. I'm glad I did! It turns out it is a 1972 model #150-0180x. The pistol is immaculate. It also came with a beautiful leather holster marked "Hunter" which appears to be brand new as well. $300.00 plus about 20.00 in gas in my little commuter car. I will post photos tomorrow. What is the value of the revolver without papers or a box?
