Hi to all, in reading Rons and Dons posts it would seem that a spring with equal thickness thin (.75 to .85) leafs, (measured at the same spot every time) would be for the 1900 .30 as well as the 02 .30 carbines with the forearm assist spring?
Then it gets kind a blurry as to application?....
.... I would think any additional thickness would be for another application, 9mm and such, and at that time probably far less common. As Don suggests, they could have increased the leaf thickness on both leaves a little and made a "catch all" spring that crossed over both ways?... any more thoughts and real time measurements as to application?
.... best, til....lat'r.....GT
