I have owned a Model 39 .22 lever gun (it looks ancient but in pretty nice shape) for several years and just today I took the magazine off to clean it --it has always been kinda gritty since I've owned it. One problem: the plug at the tip of the magazine has a small "ball" that is to be depressed to extend the outer tube of the magazine when loading ammo into the mag. The ball is stuck and will not move under any circumstances. It appears it is spring loaded, meant to press it in order to pull out the magazine tube. The ball is stuck fast as if welded in place--won't move at all. I see a small pin secures the ball and presumably the spring, I was able to drive out the tiny pin but in trying to remove or disassemble it, I am unable to get ANYTHING to move. The ball is still stuck in place. Any suggestions how to free up this ball or disassemble it? I imagine there is a problem with the spring--wish I could get it apart! Any suggestions anyone may have would be welcome.
