What's interesting about it isn't what it is. It's that it was patented in the 1956. It didn't exist for the 50 years of the Winchester 1907's manufacture, until 4 years before the Winchester 1907 was retired. And - it was introduced by Colt, not Winchester.

So no, they're not exactly the same. They don't look the same, they didn't come with the same components, didn't fire the same ammo, didn't have the same weight, didn't have the same thrust, didn't have the same method of (whatever it is that bolts and pistons do).

The only thing they had in common is that they're both semi-automatic rifles.

Good post!
