I found and picked up a beautiful used pre-CBS Marlin 39A for my 12 year old son for Christmas. He likes the action of my 336, hence, the 39A. I have an old Ruger 10/22 as well - and he likes it. He has told me he would prefer a lever-action, but he seems to like the look of the 10/22 International. I know they are both different animals, and more than likely he would be thrilled with either one. What would you get your son - the Marlin 39A or a new 10/22 International?
