Nice! I know it's an old post but I'm a newby. I had a 336A that I think was a "Wildcat"..30/'30 with a 24" barrel. Was made in 1948 or so. Narrow hammer and not drilled and tapped. I was almost 17 when I took it to a gunsmith and had it drilled and tapped against his advice. In the years before the scope I never missed. This was in the 80s and I had a Bushnell 3-9x40 and Just enough room to cock the hammer with the side of my thumb and had to get used to the pinch upon decocking. That rifle got stolen by a somebeach. I was in my mid 20s when I found another 336A with the 24" barrel. It was also made in the 40s and not drilled and tapped. That one will remain scope free but it's nice to see that vintage hammer extension.
