Exactly what it is, the first time I took the "tube" off of my Winchester 1906 it fell out. I didn't think I would ever figure out where it went!!
The only schematic I've found that shows it, is on Homestead. It's called a "magazine friction spring", and I think there's two versions, one for the .22 chambered rifles, and another for the .22 WRF. "IF" the outer tube has been replaced, good chance the spring was left off the gun, because the replacement tubes had one made as part of the tube.I was hoping it didn't come from the 94. I also had a Winchester 90-22 long #7418xx on the table about the same time. I'll check that next. Any Idea what it might be named? I'm still working on getting into Stevespages.
