Parker brass casings or hulls

[Gary Laudermilch]

So, are the Viet Nam era brass hulls worth anything to reloaders or are they trash?

They must have been used early years of Nam. All I ever saw were od green plastic shells in 1969.

The outside diameter of the 12A brass shell is the same as the standard 12 gauge paper shell. The 12B brass shell is smaller than the 12A. Guns chambered for the 12A will handle 'modern' paper and plastic shells. There's a little more to it, overall, but that is it in a nutshell.
