Rare Robin Hood Ammunition Co. Shotgun Shell 12 Gauge “Clipper”

This is a single live round of 12 Gauge ammunition manufactured by the very short lived Robin Hood Ammunition Co. in Swanton, VT circa 1906-1919.  The pink paper hull high brass cartridge is stamped “CLIPPER / 12 / R.H.A. Co” and is collector marked but otherwise very good with a plain wad.
