"Farmers" is right. Those stocks were weak, so they broke and were replaced with stocks that weren't so weak, which is why the weak ones are hard to find.

Of course, many were broken by being run over by a wagon wheel, since it was pretty common when a wagon got bogged down in mud or snow for the troops to throw their rifles under the wheels, sort of a improvised "corduroy road." Silly to sacrifice a rifle that way? Not when the wagon contained the unit's food supply.

Oh, and by the way, US Code Title 4, Chapter 1, Section 1 specifies the Flag of the United Statesicon. It doesn't specify any civilian or military versions. Of course, other organizations, official and unofficial, have their own flags, and anyone is entitled to use or fly any flag he wishes (though discretion suggests that some flags and some venues might not be compatible).
