Marlin "Varmint King" Info

I have a .222 Rem bolt action rifle, 3-shot magazine. It has a stainless steel Marlin barrel with "Varmint King" stamped on the barrel. It has a Sako action. Marlin made these rifles 1954-1957. Some books refer to this as a Model 322. This number doesn't appear anywhere on my rifle. Does anyone out there have such a rifle with "Model 322" stamped on it?
