I have never seen one. In several Ithaca sales catalogs, the 22mag 49R repeater is not mentioned. The Blue Book says "add 15% for 22mag" in the listing for 49R. I have found the Blue Book errant on several occasions. If you have one or have seen one, I want some proof and I don't mean 80 proof imagining.

It was available in 22 Magnum in the Standard and Presentation Grade in the Mid 70'S. How many they sold who knows .
